Keil & Delitzsch

On Psalms 138:3-6

There are two things for which the poet gives thanks to God: He has answered him in the days of trouble connected with his persecution by Saul and in all distresses; and by raising him to the throne, and granting him victory upon victory, and promising him the everlasting possession of the throne, He has filled him with a proud courage, so that lofty feeling has taken up its abode in his soul, which was formerly fearful about help. Just as רהב signifies impetuosity, vehemence, and then also a monster, so הרהיב signifies both to break in upon one violently and overpowerlingly (Sol 6:5; cf. Syriac arheb, Arabic arhaba, to terrify), and to make any one courageous, bold, and confident of victory. בּנפשׁי עז forms a corollary to the verb that is marked by Mugrash or Dech: so that in my soul there was עז, i.e., power, viz., a consciousness of power (cf. Jdg 5:21). The thanksgiving, which he, the king of the promise, offers to God on account of this, will be transmitted to all the kings of the earth when they shall hear (שׁמעוּ in the sense of a fut. exactum) the words of His mouth, i.e., the divine אמרה, and they shall sing of (שׁיר with בּ, like דּבּר בּ in Psa 87:3, שׂיח בּ in Psa 105:2 and frequently, הלּל בּ in Psa 44:9, הזכּיר בּ in Psa 20:8, and the like) the ways of the God of the history of salvation, they shall sing that great is the glory of Jahve. Psa 138:6 tells us by what means He has so super-gloriously manifested Himself in His leadings of David. He has shown Himself to be the Exalted One who is His all-embracing rule does not leave the lowly (cf. David's confessions in Psa 131:1; Sa2 6:22) unnoticed (Psa 113:6), but on the contrary makes him the especial object of His regard; and on the other hand even from afar (cf. Psa 139:2) He sees through (ידע as in Psa 94:11; Jer 29:23) the lofty one who thinks himself unobserved and conducts himself as if he were answerable to no higher being (Psa 10:4). In correct texts וגבה has Mugrash, and ממרחק Mercha. The form of the fut. Kal יידע is formed after the analogy of the Hiphil forms ייליל in Isa 16:7, and frequently, and ייטיב in Job 24:21; probably the word is intended to be all the more emphatic, inasmuch as the first radical, which disappears in ידע, is thus in a certain measure restored.

(Note: The Greek imperfects with the double (syllabic and temporal) augment, as ἑώρων, ἀνέῳγον, are similar. Chajuǵ also regards the first Jod in these forms as the preformative and the second as the radical, whereas Abulwald, Gramm. ch. xxvi. p. 170, explains the first as a prosthesis and the second as the preformative. According to the view of others, e.g., of Kimchi, יידע might be fut. Hiph. weakened from יהדע (יהידיע), which, apart from the unsuitable meaning, assumes a change of consonants that is all the more inadmissible as ידע itself springs from ודע. Nor is it to be supposed that יידע is modified from יידע (Luzzatto, 197), because it is nowhere written יידע.)

Matthew Henry

On Psalms 138:1-5

I. How he would praise God, compare Psa 111:1. 1. He will praise him with sincerity and zeal - "With my heart, with my whole heart, with that which is within me and with all that is within me, with uprightness of intention and fervency of affection, inward impressions agreeing with outward expressions." 2. With freedom and boldness: Before the gods will I sing praise unto thee, before the princes, and judges, and great men, either those of other nations that visited him or those of his own nation that attended on him, even in their presence. He will not only praise God with his heart, which we may do by pious ejaculations in any company, but will sing praise if there be occasion. Note, Praising God is work which the greatest of men need not be ashamed of; it is the work of angels, the work of heaven. Before the angels (so some understand it), that is, in religious assemblies, where there is a special presence of angels, Co1 11:10. 3. In the way that God had appointed: I will worship towards thy holy temple. The priests alone went into the temple; the people, at the nearest, did but worship towards it, and that they might do at a distance. Christ is our temple, and towards him we must look with an eye of faith, as Mediator between us and God, in all our praises of him. Heaven is God's holy temple, and thitherward we must lift up our eyes in all our addresses to God. Our Father in heaven.

II. What he would praise God for. 1. For the fountain of his comforts - for thy lovingkindness and for thy truth, for thy goodness and for thy promise, mercy hidden in thee and mercy revealed by thee, that God is a gracious God in himself and has engaged to be so to all those that trust in him. For thou hast magnified thy word (thy promise, which is truth) above all thy name. God has made himself known to us in many ways in creation and providence, but most clearly by his word. The judgments of his mouth are magnified even above those of his hand, and greater things are done by them. The wonders of grace exceed the wonders of nature; and what is discovered of God by revelation is much greater than what is discovered by reason. In what God had done for David his faithfulness to his work appeared more illustriously, and redounded more to his glory, than any other of his attributes. Some good interpreters understand it of Christ, the essential Word, and of his gospel, which are magnified above all the discoveries God had before made of himself to the fathers. He that magnified the law, and made that honourable, magnifies the gospel much more. 2. For the streams flowing from that fountain, in which he himself had tasted that the Lord is gracious, Psa 138:3. He had been in affliction, and he remembers, with thankfulness, (1.) The sweet communion he then had with God. He cried, he prayed, and prayed earnestly, and God answered him, gave him to understand that his prayer was accepted and should have a gracious return in due time. The intercourse between God and his saints is carried on by his promises and their prayers. (2.) The sweet communications he then had from God: Thou strengthenedst me with strength in my soul. This was the answer to his prayer, for God gives more than good words, Psa 20:6. Observe, [1.] It was a speedy answer: In the day when I cried. Note, Those that trade with heaven by prayer grow rich by quick returns. While we are yet speaking God hears, Isa 65:24. [2.] It was a spiritual answer. God gave him strength in his soul, and that is a real and valuable answer to the prayer of faith in the day of affliction. If God give us strength in our souls to bear the burdens, resist the temptations, and do the duties of an afflicted state, if he strengthen us to keep hold of himself by faith, to maintain the peace of our own minds and to wait with patience for the issue, we must own that he has answered us, and we are bound to be thankful.

III. What influence he hoped that his praising God would have upon others, Psa 138:4, Psa 138:5. David was himself a king, and therefore he hoped that kings would be wrought upon by his experiences, and his example, to embrace religion; and, if kings became religious, their kingdoms would be every way better. Now, 1. This may have reference to the kings that were neighbours to David, as Hiram and others. "They shall all praise thee." When they visited David, and, after his death, when they sought the presence of Solomon (as all the kings of the earth are expressly said to have done, Ch2 9:23), they readily joined in the worship of the God of Israel. 2. It may look further, to the calling of the Gentiles and the discipling of all nations by the gospel of Christ, of whom it is said that all kings shall fall down before him, Psa 72:11. Now it is here foretold, (1.) That the kings of the earth shall hear the words of God. All that came near David should hear them from him, Psa 119:46. In the latter days the preachers of the gospel should be sent into all the world. (2.) That then they shall praise God, as all those have reason to do that hear his word, and receive it in the light and love of it, Act 13:48. (3.) That they shall sing in the ways of the Lord, in the ways of his providence and grace towards them; they shall rejoice in God, and give glory to him, however he is pleased to deal with them in the ways of their duty and obedience to him. Note, Those that walk in the ways of the Lord have reason to sing in those ways, to go on in them with a great deal of cheerfulness, for they are ways of pleasantness, and it becomes us to be pleasant in them; and, if we are so, great is the glory of the Lord. It is very much for the honour of God that kings should walk in his ways, and that all those who walk in them should sing in them, and so proclaim to all the world that he is a good Master and his work its own wages.

Spurgeon's Treasury of David

Yea, they shall sing in the ways of the LORD. Here is a double wonder-kings in God's ways, and kings singing there. Let a man once know the ways of Jehovah, and he will find therein abundant reason for song; but the difficulty is to bring the great ones of the earth into ways so little attractive to the carnal mind. Perhaps when the Lord sends us a King David to preach, we shall yet see monarchs converted and hear their voices raised in devout adoration. For great is the glory of the LORD. This glory shall overshadow all the greatness and glory of all kings: they shall be stirred by a sight of it to obey and adore. O that Jehovah's glory were revealed even now! O that the blind eyes of men could once behold it, then their hearts would be subdued to joyful reverence. David, under a sense of Jehovah's glory, exclaimed, "I will sing" (Ps 138:1), and here he represents the kings as doing the same thing.

On Psalms 138:4-5

138:4-5 As the Lord’s glory fills the earth, the world’s population must willingly submit to him. Every king (cp. Ps 2) will join the community of praise as they hear the Lord’s ways of truth and love.
