Verse 27. - Thou hast revealed to thy servant; Hebrew, thou hast uncovered the ear of thy servant. (see note on 1 Samuel 9:15). Hath thy servant found in his heart; Hebrew, hath found his heart. The word "heart" has a wide meaning in Hebrew, embracing both our intellectual and our moral powers. Here it simply means "courage," as in, 1 Samuel 17:32. The Revised Version puts this in the margin: "Therefore hath thy servant been bold to pray this prayer."
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.
For thou, O Lord of hosts, God of Israel,.... As he is called in 2 Samuel 7:26,
hast revealed to thy servant; which he otherwise could not have known:
saying, I will build thee an house; see 2 Samuel 7:11,
therefore hath thy servant found in his heart to pray this prayer unto thee; found his heart disposed to this service, or found freedom and boldness in him to put up this prayer to God; what encouraged and emboldened him to do it was the gracious promise of God, that he would build up his family, and establish his kingdom; or otherwise he could not have taken such liberty, and used such boldness with God in prayer, as to have requested it of him.
