Keil & Delitzsch

On Psalms 121:5-8

That which holds good of "the Keeper of Israel" the poet applies believingly to himself, the individual among God's people, in Psa 121:5 after Gen 28:15. Jahve is his Keeper, He is his shade upon his right hand (היּמין as in Jdg 20:16; Sa2 20:9, and frequently; the construct state instead of an apposition, cf. e.g., Arab. jânbu 'l-grbı̂yi, the side of the western = the western side), which protecting him and keeping him fresh and cool, covers him from the sun's burning heat. על, as in Psa 109:6; Psa 110:5, with the idea of an overshadowing that screens and spreads itself out over anything (cf. Num 14:9). To the figure of the shadow is appended the consolation in Psa 121:6. הכּה of the sun signifies to smite injuriously (Isa 49:10), plants, so that they wither (Psa 102:5), and the head (Jon 4:8), so that symptoms of sun-stroke (Kg2 4:19, Judith 8:2f.) appears. The transferring of the word of the moon is not zeugmatic. Even the moon's rays may become insupportable, may affect the eyes injuriously, and (more particularly in the equatorial regions) produce fatal inflammation of the brain.

(Note: Many expositors, nevertheless, understand the destructive influence of the moon meant here of the nightly cold, which is mentioned elsewhere in the same antithesis. Gen 31:40; Jer 36:30. De Sacy observes also: On dit quelquefois d'un grand froid, comme d'un grand chaud, qu'il est brulant. The Arabs also say of snow and of cold as of fire: jaḥrik, it burns.)

From the hurtful influences of nature that are round about him the promise extends in Psa 121:7-8 in every direction. Jahve, says the poet to himself, will keep (guard) thee against all evil, of whatever kind it may be and whencesoever it may threaten; He will keep thy soul, and therefore thy life both inwardly and outwardly; He will keep (ישׁמר־, cf. on the other hand ישׁפּט־ in Psa 9:9) thy going out and coming in, i.e., all thy business and intercourse of life (Deu 28:6, and frequently); for, as Chrysostom observes, ἐν τούτοις ὁ βίος ἅπας, ἐν εἰσόδοις καὶ ἐξόδοις, therefore: everywhere and at all times; and that from this time forth even for ever. In connection with this the thought is natural, that the life of him who stands under the so universal and unbounded protection of eternal love can suffer no injury.

Matthew Henry

On Psalms 121:1-8

This psalm teaches us,

I. To stay ourselves upon God as a God of power and a God all-sufficient for us. David did so and found the benefit of it. 1. We must not rely upon creatures, upon men and means, instruments and second causes, nor make flesh our arm: "Shall I lift up my eyes to the hills?" - so some read it. "Does my help come thence? Shall I depend upon the powers of the earth, upon the strength of the hills, upon princes and great men, who, like hills, fill the earth, and hold up their heads towards heaven? No; in vain is salvation hoped for from hills and mountains, Jer 3:23. I never expect help to come from them; my confidence is in God only." We must lift up our eyes above the hills (so some read it); we must look beyond instruments to God, who makes them that to us which they are. 2. We must see all our help laid up in God, in his power and goodness, his providence and grace; and from him we must expect it to come: "My help comes from the Lord; the help I desire is what he sends, and from him I expect it in his own way and time. If he do not help, no creature can help; if he do, no creature can hinder, can hurt." 3. We must fetch in help from God, by faith in his promises, and a due regard to all his institutions: "I will lift up my eyes to the hills" (probably he meant the hills on which the temple was built, Mount Moriah, and the holy hill of Zion, where the ark of the covenant, the oracle, and the altars were); "I will have an eye to the special presence of God in his church, and with his people (his presence by promise) and not only to his common presence." When he was at a distance he would look towards the sanctuary (Psa 28:2; Psa 42:6); thence comes our help, from the word and prayer, from the secret of his tabernacle. My help cometh from the Lord (so the word is, Psa 121:2), from before the Lord, or from the sight and presence of the Lord. "This (says Dr. Hammond) may refer to Christ incarnate, with whose humanity the Deity being inseparably united, God is always present with him, and, through him, with us, for whom, sitting at God's right hand, he constantly maketh intercession." Christ is called the angel of his presence, that saved his people, Isa 63:9. 4. We must encourage our confidence in God with this that he made heaven and earth, and he who did that can do any thing. He made the world out of nothing, himself alone, by a word's speaking, in a little time, and all very good, very excellent and beautiful; and therefore, how great soever our straits and difficulties are, he has power sufficient for our succour and relief. He that made heaven and earth is sovereign Lord of all the hosts of both, and can make use of them as he pleases for the help of his people, and restrain them when he pleases from hurting his people.

II. To comfort ourselves in God when our difficulties and dangers are greatest. It is here promised that if we put our trust in God, and keep in the way of our duty, we shall be safe under his protection, so that no real evil, no mere evil, shall happen to us, nor any affliction but what God sees good for us and will do us good by. 1. God himself has undertaken to be our protector: The Lord is thy keeper, Psa 121:5. Whatever charge he gives his angels to keep his people, he has not thereby discharged himself, so that, whether every particular saint has an angel for his guardian or no, we are sure he has God himself for his guardian. It is infinite wisdom that contrives, and infinite power that works, the safety of those that have put themselves under God's protection. Those must needs be well kept that have the Lord for their keeper. If, by affliction, they be made his prisoners, yet still he is their keeper. 2. The same that is the protector of the church in general is engaged for the preservation of every particular believer, the same wisdom, the same power, the same promises. He that keepeth Israel (Psa 121:4) is thy keeper, Psa 121:5. The shepherd of the flock is the shepherd of every sheep, and will take care that not one, even of the little ones, shall perish. 3. He is a wakeful watchful keeper: "He that keepeth Israel, that keepeth thee, O Israelite! shall neither slumber nor sleep; he never did, nor ever will, for he is never weary; he not only does not sleep, but he does not so much as slumber; he has not the least inclination to sleep." 4. He not only protects those whom he is the keeper of, but he refreshes them: He is their shade. The comparison has a great deal of gracious condescension in it; the eternal Being who is infinite substance is what he is in order that he may speak sensible comfort to his people, promises to be their umbra - their shadow, to keep as close to them as the shadow does to the body, and to shelter them from the scorching heat, as the shadow of a great rock in a weary land, Isa 32:2. Under this shadow they may sit with delight and assurance, Sol 2:3. 5. He is always near to his people for their protection and refreshment, and never at a distance; he is their keeper and shade on their right hand; so that he is never far to seek. The right hand is the working hand; let them but turn themselves dexterously to their duty, and they shall find God ready to them, to assist them and give them success, Psa 16:8. 6. He is not only at their right hand, but he will also keep the feet of his saints, Sa1 2:9. He will have an eye upon them in their motions: He will not suffer thy foot to be moved. God will provide that his people shall not be tempted above what they are able, shall not fall into sin, though they may be very near it (Psa 73:2, Psa 73:23), shall not fall into trouble, though there be many endeavouring to undermine them by fraud or over throw them by force. He will keep them from being frightened, as we are when we slip or stumble and are ready to fall. 7. He will protect them from all the malignant influences of the heavenly bodies (Psa 121:6): The sun shall not smite thee with his heat by day nor the moon with her cold and moisture by night. The sun and moon are great blessings to mankind, and yet (such a sad change has sin made in the creation) even the sun and moon, though worshipped by a great part of mankind, are often instruments of hurt and distemper to human bodies; God by them often smites us; but his favour shall interpose so that they shall not damage his people. He will keep them night and day (Isa 27:3), as he kept Israel in the wilderness by a pillar of cloud by day, which screened them from the heat of the sun, and of fire by night, which probably diffused a genial warmth over the whole camp, that they might not be prejudiced by the cold and damp of the night, their father Jacob having complained (Gen 31:40) that by day the drought consumed him and the frost by night. It may be understood figuratively: "Thou shalt not be hurt either by the open assaults of thy enemies, which are as visible as the scorching beams of the sun, or by their secret treacherous attempts, which are like the insensible insinuations of the cold by night." 8. His protection will make them safe in every respect: "The Lord shall preserve thee from all evil, the evil of sin and the evil of trouble. He shall prevent the evil thou fearest, and shall sanctify, remove, or lighten, the evil thou feelest. He will keep thee from doing evil (Co2 13:7), and so far from suffering evil that whatever affliction happens to thee there shall be no evil in it. Even that which kills shall not hurt." 9. It is the spiritual life, especially, that God will take under his protection: He shall preserve thy soul. All souls are his; and the soul is the man, and therefore he will with a peculiar care preserve them, that they be not defiled by sin and disturbed by affliction. He will keep them by keeping us in the possession of them; and he will preserve them from perishing eternally. 10. He will keep us in all our ways: "He shall preserve thy going out and thy coming in. Thou shalt be under his protection in all thy journeys and voyages, outward-bound or homeward-bound, as he kept Israel in the wilderness, in their removes and rests. He will prosper thee in all thy affairs at home and abroad, in the beginning and in the conclusion of them. He will keep thee in life and death, thy going out and going on while thou livest and thy coming in when thou diest, going out to thy labour in the morning of thy days and coming home to thy rest when the evening of old age calls thee in," Psa 104:23. 11. He will continue his care over us from this time forth and even for evermore. It is a protection for life, never out of date. "He will be thy guide even unto death, and will then hide thee in the grave, hide thee in heaven. He will preserve thee in his heavenly kingdom." God will protect his church and his saints always, even to the end of the world. The Spirit, who is their preserver and comforter, shall abide with them for ever.

Spurgeon's Treasury of David

The Lord is thy keeper. Here the preserving One, who had been spoken of by pronouns in the two previous verses, is distinctly named-Jehovah is thy keeper. What a mint of meaning lies here: the sentence is a mass of bullion, and when coined and stamped with the king's name it will bear all our expenses between our birthplace on earth and our rest in heaven. Here is a glorious person-Jehovah, assuming a gracious office and fulfilling it in person,-Jehovah is thy keeper, in behalf of a favoured individual-thy, and a firm assurance of revelation that it is even so at this hour-Jehovah is thy keeper. Can we appropriate the divine declaration? If so, we may journey onward to Jerusalem and know no fear; yea, we may journey through the valley of the shadow of death and fear no evil. The Lord is thy shade upon thy right hand. A shade gives protection from burning heat and glaring light. We cannot bear too much blessing; even divine goodness, which is a right hand dispensation, must be toned down and shaded to suit our infirmity, and this the Lord will do for us. He will bear a shield before us, and guard the right arm with which we fight the foe. That member which has the most of labour shall have the most of protection. When a blazing sun pours down its burning beams upon our heads the Lord Jehovah himself will interpose to shade us, and that in the most honourable manner, acting as our right hand attendant, and placing us in comfort and safety. "The Lord at thy right hand shall smite through kings". How different this from the portion of the ungodly ones who have Satan standing at their right hand, and of those of whom Moses said, "their defence has departed from them". God is as near us as our shadow, and we are as safe as angels.

Tyndale Study Notes

On Psalms 121:4-8

121:4-6 The Creator (121:2) is the guardian of Israel. • God stands beside Israel, supporting and caring for the godly (see 16:7-8). • Both the sun and the moon were regarded as deities in the ancient Near East, but the Creator limits their power. They, too, praise the Lord (148:3).

121:4 God watches over his own, even and especially when they face many troubles (12:5, 7; 69:29; 91:14; 146:9).
