And this was yet a small thing in thy sight, O Lord GOD; but thou hast spoken also of thy servant's house for a great while to come. And is this the manner of {h} man, O Lord GOD?

(h) Does this not come rather from your free mercy, than from any worthiness that can be in man?

Wesley's Notes

7:19 This - Which thou hast already done for me, that thou hast brought me hitherto, to that pitch of honour, and peace, and prosperity, in which through thy favour I now stand. Was small - Though it was more than I deserved, or could expect, yet thou didst not think it enough for thee to give to me. A great while - For many future ages, and indeed to all eternity. Is this, and c. - Do men use to deal so kindly with their inferiors, as thou hast done with me? No: this is the prerogative of divine grace.

Jamieson-Fausset-Brown Bible Commentary

19. is this the manner of man, O Lord God?-that is, is it customary for men to show such condescension to persons so humble as I am? (See 1Ch 17:17.)

Matthew Henry's Concise Commentary

7:18-29 David's prayer is full of the breathings of devout affection toward God. He had low thoughts of his own merits. All we have, must be looked upon as Divine gifts. He speaks very highly and honourably of the Lord's favours to him. Considering what the character and condition of man is, we may be amazed that God should deal with him as he does. The promise of Christ includes all; if the Lord God be ours, what more can we ask, or think of? Eph 3:20. He knows us better than we know ourselves; therefore let us be satisfied with what he has done for us. What can we say more for ourselves in our prayers, than God has said for us in his promises? David ascribes all to the free grace of God. Both the great things He had done for him, and the great things He had made known to him. All was for his word's sake, that is, for the sake of Christ the eternal Word. Many, when they go to pray, have their hearts to seek, but David's heart was found, that is, it was fixed; gathered in from its wanderings, entirely engaged to the duty, and employed in it. That prayer which is from the tongue only, will not please God; it must be found in the heart; that must be lifted up and poured out before God. He builds his faith, and hopes to speed, upon the sureness of God's promise. David prays for the performance of the promise. With God, saying and doing are not two things, as they often are with men; God will do as he hath said. The promises of God are not made to us by name, as to David, but they belong to all who believe in Jesus Christ, and plead them in his name.
