Keil & Delitzsch

On Psalms 138:7-8

Out of these experiences-so important for all mankind - of David, who has been exalted by passing through humiliation, there arise from him confident hopes concerning the future. The beginning of this strophe calls Psa 23:4 to mind. Though his way may lead through the midst of heart - oppressing trouble, Jahve will loose these bands of death and quicken him afresh (חיּה as in Psa 30:4; Psa 71:20, and frequently). Though his enemies may rage, Jahve will stretch forth His hand threateningly and tranquillizingly over their wrath, and His right hand will save him. ימינך is the subject according to Psa 139:10 and other passages, and not (for why should it be supposed to be this?) accus. instrumenti (vid., Psa 60:7). In Psa 138:8 יגמר is intended just as in Psa 57:3 : the word begun He will carry out, ἐπιτελεῖν (Phi 1:6); and בּעדי (according to its meaning, properly: covering me) is the same as עלי in that passage (cf. Psa 13:6; 142:8). The pledge of this completion is Jahve's everlasting mercy, which will not rest until the promise is become perfect truth and reality. Thus, therefore, He will not leave, forsake the works of His hands (vid., Psa 90:16.), i.e., as Hengstenberg correctly explains, everything that He has hitherto accomplished for David, from his deliverance out of the hands of Saul down to the bestowment of the promise - He will not let one of His works stand still, and least of all one that has been so gloriously begun. הרפּה (whence תּרף) signifies to slacken, to leave slack, i.e., leave uncarried out, to leave to itself, as in Neh 6:3. אל expresses a negation with a measure of inward excitement.

Matthew Henry

On Psalms 138:6-8

David here comforts himself with three things: -

I. The favour God bears to his humble people (Psa 138:6): Though the Lord be high, and neither needs any of his creatures nor can be benefited by them, yet has he respect unto the lowly, smiles upon them as well pleased with them, overlooks heaven and earth to cast a gracious look upon them (Isa 57:15; Isa 66:1), and, sooner or later, he will put honour upon them, while he knows the proud afar off, knows them, but disowns them and rejects them, how proudly soever they pretend to his favour. Dr. Hammond makes this to be the sum of that gospel which the kings of the earth shall hear and welcome - that penitent sinners shall be accepted of God, but the impenitent cast out; witness the instance of the Pharisee and the publican, Lu. 18.

II. The care God takes of his afflicted oppressed people, Psa 138:7. David, though a great and good man, expects to walk in the midst of trouble, but encourages himself with hope, 1. That God would comfort him: "When my spirit is ready to sink and fail, thou shalt revive me, and make me easy and cheerful under my troubles." Divine consolations have enough in them to revive us even when we walk in the midst of troubles and are ready to die away for fear. 2. That he would protect him, and plead his cause: "Thou shalt stretch forth thy hand, though not against my enemies to destroy them, yet against the wrath of my enemies, to restrain that and set bounds to it." 3. That he would in due time work deliverance for him: Thy right hand shall save me. As he has one hand to stretch out against his enemies, so he has another to save his own people. Christ is the right hand of the Lord, that shall save all those who serve him.

III. The assurance we have that whatever good work God has begun in and for his people he will perform it (Psa 138:8): The Lord will perfect that which concerns me, 1. That which is most needful for me; and he knows best what is so. We are careful and cumbered about many things that do not concern us, but he knows what are the things that really are of consequence to us (Mat 6:32) and he will order them for the best. 2. That which we are most concerned about. Every good man is most concerned about his duty to God and his happiness in God, that the former may be faithfully done and the latter effectually secured; and if indeed these are the things that our hearts are most upon, and concerning which we are most solicitous, there is a good work begun in us, and he that has begun it will perfect it, we may be confident he will, Phi 1:6. Observe, (1.) What ground the psalmist builds this confidence upon: Thy mercy, O Lord! endures for ever. This he had made very much the matter of his praise (Psa 13:6), and therefore he could here with the more assurance make it the matter of his hope. For, if we give God the glory of his mercy, we may take to ourselves the comfort of it. Our hopes that we shall persevere must be founded, not upon our own strength, for that will fail us, but upon the mercy of God, for that will not fail. It is well pleaded, "Lord, thy mercy endures for ever; let me be for ever a monument of it." (2.) What use he makes of this confidence; it does not supersede, but quicken prayer; he turns his expectation into a petition: "Forsake not, do not let go, the work of thy own hands. Lord, I am the work of thy own hands, my soul is so, do not forsake me; my concerns are so, do not lay by thy care of them." Whatever good there is in us it is the work of God's own hands; he works in us both to will and to do; it will fail if he forsake it; but his glory, as Jehovah, a perfecting God, is so much concerned in the progress of it to the end that we may in faith pray, "Lord, do not forsake it." Whom he loves he loves to the end; and, as for God, his work is perfect.

Spurgeon's Treasury of David

Though I walk in the midst of trouble, thou wilt revive me. If I am walking there now, or shall be doing so in years to come, I have no cause for fear; for God is with me, and will give me new life. When we are somewhat in trouble it is bad enough, but it is worse to penetrate into the centre of that dark continent and traverse its midst: yet in such a case the believer makes progress, for he walks; he keeps to a quiet pace, for he does no more than walk; and he is not without the best of company, for his God is near to pour fresh life into him. It is a happy circumstance that, if God be away at any other time, yet he is pledged to be with us in trying hours: "when thou passest through the rivers I will be with thee." He is in a blessed condition who can confidently use the language of David,-"thou wilt revive me." He shall not make his boast of God in vain: he shall be kept alive, and made more alive than ever. How often has the Lord quickened us by our sorrows! Are they not his readiest means of exciting to fulness of energy the holy life which dwells within us? If we receive reviving, we need not regret affliction. When God revives us, trouble will never harm us. Thou shalt stretch forth thine hand against the wrath of mine enemies, and thy right hand shall save me. This is the fact which would revive fainting David. Our foes fall when the Lord comes to deal with them; he makes short work of the enemies of his people,-with one hand he routs them. His wrath soon quenches their wrath; his hand stays their hand. Adversaries may be many, and malicious, and mighty; but our glorious Defender has only to stretch out his arm and their armies vanish. The sweet singer rehearses his assurance of salvation, and sings of it in the ears of the Lord, addressing him with this confident language. He will be saved,-saved dexterously, decidedly, divinely; he has no doubt about it. God's right hand cannot forget its cunning; Jerusalem is his chief joy, and he will defend his own elect.
