Jamieson, Fausset & Brown

On Genesis 15:4-8

This shall not be thine heir - To the first part of his address no reply was given; but having renewed it in a spirit of more becoming submission, "whereby shall I know that I shall inherit it" [Gen 15:8], he was delighted by a most explicit promise of Canaan, which was immediately confirmed by a remarkable ceremony.

John Gill

On Genesis 15:6

And he believed in the Lord,.... The Targums of Onkelos and Jonathan are,"in the Word of the Lord;''in the essential Word of the Lord, in Christ the Lord his righteousness; he believed in the promise of God, that he should have a seed, and a very numerous one; he believed that the Messiah would spring from his seed; he believed in him as his Saviour and Redeemer; he believed in him for righteousness, and he believed in his righteousness as justifying him before God:

and he counted it to him for righteousness; not the act of his faith, but the object of it; and not the promise he believed, but what was promised, and his faith received, even Christ and his righteousness this was imputed to him without works, and while he was an uncircumcised person, for the proof of which the apostle produces this passage, Romans 4:3; wherefore this is not to be understood of any action of his being esteemed and accounted a righteous one, and he pronounced and acknowledged a righteous person on account of it; for Abram was not justified before God by his own works, but by the righteousness of faith, as all that believe are, that is, by the righteousness of Christ revealed to faith, and received by it: what is imputed is without a man, and the imputation of it depends upon the will of another; such the righteousness of Christ without works imputed by God the Father. This is the first time we read of believing, and as early do we hear of imputed righteousness.

Keil & Delitzsch

On Genesis 15:1-6

The words of Jehovah run thus: "Fear not, Abram: I am a shield to thee, thy reward very much." הרבּה an inf. absol., generally used adverbially, but here as an adjective, equivalent to "thy very great reward." The divine promise to be a shield to him, that is to say, a protection against all enemies, and a reward, i.e., richly to reward his confidence, his ready obedience, stands here, as the opening words "after these things" indicate, in close connection with the previous guidance of Abram. Whilst the protection of his wife in Egypt was a practical pledge of the possibility of his having a posterity, and the separation of Lot, followed by the conquest of the kings of the East, was also a pledge of the possibility of his one day possessing the promised land, there was as yet no prospect whatever of the promise being realized, that he should become a great nation, and possess an innumerable posterity. In these circumstances, anxiety about the future might naturally arise in his mind. To meet this, the word of the Lord came to him with the comforting assurance, "Fear not, I am thy shield." But when the Lord added, "and thy very great reward," Abram could only reply, as he thought of his childless condition: "Lord Jehovah, what wilt Thou give me, seeing I go childless?" Of what avail are all my possessions, wealth, and power, since I have no child, and the heir of my house is Eliezer the Damascene? משׁק, synonymous with ממשׁק (Zep 2:9), possession, or the seizure of possession, is chosen on account of its assonance with דּמּשׂק. בּן־משׁק, son of the seizing of possession = seizer of possession, or heir. Eliezer of Damascus (lit., Damascus viz., Eliezer): Eliezer is an explanatory apposition to Damascus, in the sense of the Damascene Eliezer; though דּמּשׂק, on account of its position before אליעזר, cannot be taken grammatically as equivalent to דּמּשׂקי.

(Note: The legend of Abram having been king in Damascus appears to have originated in this, though the passage before us does not so much as show that Abram obtained possession of Eliezer on his way through Damascus.)

To give still more distinct utterance to his grief, Abram adds (Gen 15:3): "Behold, to me Thou hast given no seed; and lo, an inmate of my house (בּן־בּיתי in distinction from יליד־בּית, home-born, Gen 14:14) will be my heir." The word of the Lord then came to him: "Not he, but one who shall come forth from thy body, he will be thine heir." God then took him into the open air, told him to look up to heaven, and promised him a posterity as numerous as the innumerable host of stars (cf. Gen 22:17; Gen 24:4; Exo 32:13, etc.). Whether Abram at this time was "in the body or out of the body," is a matter of no moment. The reality of the occurrence is the same in either case. This is evident from the remark made by Moses (the historian) as to the conduct of Abram in relation to the promise of God: "And he believed in Jehovah, and He counted it to him for righteousness." In the strictly objective character of the account in Genesis, in accordance with which the simple facts are related throughout without any introduction of subjective opinions, this remark appears so striking, that the question naturally arises, What led Moses to introduce it? In what way did Abram make known his faith in Jehovah? And in what way did Jehovah count it to him as righteousness? The reply to both questions must not be sought in the New Testament, but must be given or indicated in the context. What reply did Abram make on receiving the promise, or what did he do in consequence? When God, to confirm the promise, declared Himself to be Jehovah, who brought him out of Ur of the Chaldees to give him that land as a possession, Abram replied, "Lord, whereby shall I know that I shall possess it?" God then directed him to "fetch a heifer of three years old," etc.; and Abram fetched the animals required, and arranged them (as we may certainly suppose, thought it is not expressly stated) as God had commanded him. By this readiness to perform what God commanded him, Abram gave a practical proof that he believed Jehovah; and what God did with the animals so arranged was a practical declaration on the part of Jehovah, that He reckoned this faith to Abram as righteousness.

The significance of the divine act is, finally, summed up in Gen 15:18, in the words, "On that day Jehovah made a covenant with Abram." Consequently Jehovah reckoned Abram's faith to him as righteousness, by making a covenant with him, by taking Abram into covenant fellowship with Himself. האמין, from אמן to continue and the preserve, to be firm and to confirm, in Hiphil to trust, believe (πιστεύσιν), expresses "that state of mind which is sure of its object, and relies firmly upon it;" and as denoting conduct towards God, as "a firm, inward, personal, self-surrendering reliance upon a personal being, especially upon the source of all being," it is construed sometimes with ל (e.g., Deu 9:23), but more frequently with בּ (Num 14:11; Num 20:12; Deu 1:32), "to believe the Lord," and "to believe on the Lord," to trust in Him, - πιστεύειν ἐπὶ τὸν Θεόν, as the apostle has more correctly rendered the ἐπίστευσεν τῷ Θεῷ of the lxx (vid., Rom 4:5). Faith therefore is not merely assensus, but fiducia also, unconditional trust in the Lord and His word, even where the natural course of events furnishes no ground for hope or expectation. This faith Abram manifested, as the apostle has shown in Rom 4; and this faith God reckoned to him as righteousness by the actual conclusion of a covenant with him. צדקה, righteousness, as a human characteristic, is correspondence to the will of God both in character and conduct, or a state answering to the divine purpose of a man's being. This was the state in which man was first created in the image of God; but it was lost by sin, through which he placed himself in opposition to the will of God and to his own divinely appointed destiny, and could only be restored by God. When the human race had universally corrupted its way, Noah alone was found righteous before God (Gen 7:1), because he was blameless and walked with God (Gen 6:9). This righteousness Abram acquired through his unconditional trust in the Lord, his undoubting faith in His promise, and his ready obedience to His word. This state of mind, which is expressed in the words בּיהוה האמין, was reckoned to him as righteousness, so that God treated him as a righteous man, and formed such a relationship with him, that he was placed in living fellowship with God. The foundation of this relationship was laid in the manner described in Gen 15:7-11.

Matthew Henry

On Genesis 15:2-6

We have here the assurance given to Abram of a numerous offspring which should descend from him, in which observe,

I. Abram's repeated complaint, Gen 15:2, Gen 15:3. This was that which gave occasion to this promise. The great affliction that sat heavy upon Abram was the want of a child; and the complaint of this he here pours out before the Lord, and shows before him his trouble, Psa 142:2. Note, Though we must never complain of God, yet we have leave to complain to him, and to be large and particular in the statement of our grievances; and it is some ease to a burdened spirit to open its case to a faithful and compassionate friend: such a friend God is, whose ear is always open. Now his complaint is four-fold: - 1. That he had no child (Gen 15:3): Behold, to me thou hast given no seed; not only no son, but no seed; if he had had a daughter, from her the promised Messiah might have come, who was to be the seed of the woman; but he had neither son nor daughter. He seems to lay an emphasis on that, to me. His neighbours were full of children, his servants had children born in his house. "But to me," he complains, "thou hast given none;" and yet God had told him he should be a favourite above all. Note, Those that are written childless must see God writing them so. Again, God often withholds those temporal comforts from his own children which he gives plentifully to others that are strangers to him. 2. That he was never likely to have any, intimated in that I go, or "I am going, childless, going into years, going down the hill apace; nay, I am going out of the world, going the way of all the earth. I die childless," so the Septuagint, "I leave the world, and leave no child behind me." 3. That his servants were for the present and were likely to be to him instead of sons. While he lived, the steward of his house was Eliezer of Damascus; to him he committed the care of his family and estate, who might be faithful, but only as a servant, not as a son. When he died, one born in his house would be his heir, and would bear rule over all that for which he had laboured, Ecc 2:18, Ecc 2:19, Ecc 2:21. God had already told him that he would make of him a great nation (Gen 12:2), and his seed as the dust of the earth (Gen 13:16); but he had left him in doubt whether it should be his seed begotten or his seed adopted, by a son of his loins or only a son of his house. "Now, Lord," says Abram, "if it be only an adopted son it must be one of my servants, which will reflect disgrace upon the promised seed, that is to descend from him." Note, While promised mercies are delayed our unbelief and impatience are apt to conclude them denied. 4. That the want of a son was so great a trouble to him that it took away the comfort of all his enjoyments: "Lord, what wilt thou give me? All is nothing to me, if I have not a son." Now, If we suppose that Abram looked no further than a temporal comfort, this complaint was culpable. God had, by his providence, given him some good things, and more by his promise; and yet Abram makes no account of them, because he has not a son. It did very ill become the father of the faithful to say, What wilt thou give me, seeing I go childless, immediately after God had said, I am thy shield, and thy exceedingly great reward. Note, Those do not rightly value the advantages of their covenant-relation to God and interest in him who do not think them sufficient whatever. But, (2.) If we suppose that Abram, herein, had a eye to the promised seed, the importunity of his desire was very commendable: all was nothing to him, if he had not the earnest of that great blessing, and an assurance of his relation to the Messiah, of which God had already encouraged him to maintain the expectation. He has wealth, and victory, and honour; but, while he is kept in the dark about the main matter, it is all nothing to him. Note, Till we have some comfortable evidence of our interest in Christ and the new covenant, we should not rest satisfied with any thing else. "This, and the other, I have; but what will all this avail me, if I go Christless?" Yet thus far the complaint was culpable, that there was some diffidence of the promise at the bottom of it, and a weariness of waiting God's time. Note, True believers sometimes find it hard to reconcile God's promises and his providences, when they seem to disagree.

II. God's gracious answer to this complaint. To the first part of the complaint (Gen 15:2) God gave no immediate answer, because there was something of fretfulness in it; but, when he renews his address somewhat more calmly (Gen 15:3), God answered him graciously. Note, If we continue instant in prayer, and yet pray with a humble submission to the divine will, we shall not seek in vain. 1. God gave him an express promise of a son, Gen 15:4. This that is born in thy house shall not be thy heir, as thou fearest, but one that shall come forth out of thy own bowels shall be thy heir. Note, (1.) God makes heirs; he says, "This shall not, and this shall;" and whatever men devise and design, in settling their estates, God's counsel shall stand. (2.) God is often better to us than our own fears, and gives the mercy we had long despaired of. 2. To affect him the more with this promise, he took him out, and showed him the stars (this vision being early in the morning, before day), and then tells him, So shall thy seed be, Gen 15:5. (1.) So numerous; the stars seem innumerable to a common eye: Abram feared he should have no child at all, but God assured him that the descendants from his loins should be so many as not to be numbered. (2.) So illustrious, resembling the stars in splendour; for to them pertained the glory, Rom 9:4. Abram's seed, according to his flesh, were like the dust of the earth (Gen 13:16), but his spiritual seed are like the stars of heaven, not only numerous, but glorious, and very precious.

III. Abram's firm belief of the promise God now made him, and God's favourable acceptance of his faith, Gen 15:6. 1. He believed in the Lord, that is, he believed the truth of that promise which God had now made him, resting upon the irresistible power and the inviolable faithfulness of him that made it. Hath he spoken, and shall he not make it good? Note, Those who would have the comfort of the promises must mix faith with the promises. See how the apostle magnifies this faith of Abram, and makes it a standing example, Rom 4:19-21. He was not weak in faith; he staggered not at the promise; he was strong in faith; he was fully persuaded. The Lord work such a faith in every one of us! Some think that his believing in the Lord respected, not only the Lord promising, but the Lord promised, the Lord Jesus, the Mediator of the new covenant. He believed in him, that is, received and embraced the divine revelation concerning him, and rejoiced to see his day, though at so great a distance, Joh 8:56. 2. God counted it to him for righteousness; that is, upon the score of this he was accepted of God, and, as the rest of the patriarchs, by faith he obtained witness that he was righteous, Heb 11:4. This is urged in the New Testament to prove that we are justified by faith without the works of the law (Rom 4:3; Gal 3:6); for Abram was so justified while he was yet uncircumcised. If Abram, that was so rich in good works was not justified by them, but by his faith, much less can we, that are so poor in them. This faith, which was imputed to Abram for righteousness, had lately struggled with unbelief (Gen 15:2), and, coming off a conqueror, it was thus crowned, thus honoured. Note, A fiducial practical acceptance of, and dependence upon, God's promise of grace and glory, in and through Christ, is that which, according to the tenour of the new covenant, gives us a right to all the blessings contained in that promise. All believers are justified as Abram was, and it was his faith that was counted to him for righteousness.

Tyndale Study Notes

On Genesis 15:6

15:6 And Abram believed: God made his covenant with a believer; the statement does not indicate when Abram came to faith. The Hebrew text does not link Abram’s belief with the promise of the stars; it just says parenthetically that Abram believed God. Abram already had faith; his departure from Ur was his first great act that demonstrated it (see Heb 11:8-10). • God counted him as righteous because of his faith: This central statement about Abram’s saving faith is quoted three times in the New Testament (Rom 4:3; Gal 3:6; Jas 2:23) to support the doctrine of righteousness before God by faith (see also Rom 4:22-23).
