| Matthew Henry's Concise Commentary 109:21-31 The psalmist takes God's comforts to himself, but in a very humble manner. He was troubled in mind. His body was wasted, and almost worn away. But it is better to have leanness in the body, while the soul prospers and is in health, than to have leanness in the soul, while the body is feasted. He was ridiculed and reproached by his enemies. But if God bless us, we need not care who curses us; for how can they curse whom God has not cursed; nay, whom he has blessed? He pleads God's glory, and the honour of his name. Save me, not according to my merit, for I pretend to none, but according to thy-mercy. He concludes with the joy of faith, in assurance that his present conflicts would end in triumphs. Let all that suffer according to the will of God, commit the keeping of their souls to him. Jesus, unjustly put to death, and now risen again, is an Advocate and Intercessor for his people, ever ready to appear on their behalf against a corrupt world, and the great accuser.
Pulpit CommentaryVerses 21-29. - The psalmist now turns to God in prolonged prayer, setting forth his needs (vers. 22-25), and entreating for help (ver. 26), deliverance (ver. 21), blessing (ver. 28), and triumph over his enemies (ver. 29). Verse 21. - But do thou for me; or, "deal thou with me" (see the Revised Version). O God the Lord; literally, Jehovah the Lord, as in Psalm 68:20; Psalm 140:7; Psalm 141:8; Habakkuk 3:19. For thy Name's sake; i.e. suitably to thy Name - according to thy historically manifested attributes. Because thy mercy is good, deliver thou me. A variant echo of the preceding clause (comp. Psalm 69:16).
Gill's Exposition of the Entire BibleBut do thou for me, O God the Lord, for thy name's sake,.... The sense of the petition is, and which is a prayer of Christ as man, that the Lord God would take his part, be on his side, be present with him, work with him, help and assist him, and that for his own honour and glory, for his truth and faithfulness sake, who had promised him help and assistance, Psalm 89:21. Because thy mercy is good, deliver thou me; or "thy kindness" (g); meaning the lovingkindness of God to Christ, which he always bore to him, and was eminently and superlatively good; which he makes use of as an argument for his deliverance out of all his troubles, and from death itself; see Psalm 69:14. (g) "benignitas tua", Musculus, Junius & Tremellius, Piscator.
The Treasury of David21 But do thou for me, O God the Lord, for thy name's sake: because thy mercy is good, deliver thou me. 22 For I am poor and needy, and my heart is wounded within me. 23 I am gone like the shadow when it declineth: I am tossed up and down as the locust. 24 My knees are weak through fasting; and my flesh faileth of fatness. 25 I became also a reproach unto them: when they looked upon me they shaked their heads. 26 Help me, O Lord my God: O save me according to thy mercy: 27 That they may know that this is thy hand; that thou, Lord, hast done it. 28 Let them curse, but bless thou; when they arise, let them be ashamed; but let thy servant rejoice. 29 Let mine adversaries be clothed with shame, and let them cover themselves with their own confusion, as with a mantle. 30 I will greatly praise the Lord with my mouth; yea, I will praise him among the multitude. 31 For he shall stand at the right hand of the poor, to save him from those that condemn his soul. Psalm 109:21 "But do thou for me, O God the Lord, for thy name's sake." How eagerly he turns from his enemies to his God! He sets the great Thou in opposition to all his adversaries, and you see at once that his heart is at rest. The words are very indistinct, and though our version may not precisely translate them, yet it in a remarkable manner hits upon the sense and upon the obscurity which hang over it. "Do thou for me" - what shall he do? Why, do whatever he thinks fit. He leaves himself in the Lord's hands, dictating nothing, but quite content so long as his God will but undertake for him. His plea is not his own merit, but the name. The saints have always felt this to be their most mighty plea. God himself has performed his grandest deeds of grace for the honour of his name, and his people know that this is the most potent argument with him. What the Lord himself has guarded with sacred jealousy we should reverence with our whole hearts and rely upon without distrust. "Because thy mercy is good, deliver thou me." Not because I am good, but because thy mercy is good: see how the saints fetch their pleadings in prayer from the Lord himself. God's mercy is the star to which the Lord's people turn their eye when they are tossed with tempest and not comforted, for the peculiar bounty and goodness of that mercy have a charm for weary hearts. When man has no mercy we shall still find it in God. When man would devour we may look to God to deliver. His name and his mercy are two firm grounds for hope, and happy are those who know how to rest upon them. Psalm 109:22 continued...
