Wherefore thou art great, O Lord God,.... In his name, nature, persons, and perfections, purposes, promises, and works:

for there is none like thee; for his essence and attributes, for his greatness and goodness, for what he is in himself, for what he is to his people, and has done for them:

neither is there any God beside thee; there is but one God, the living and true God, the former and maker of all things; all others are but fictitious and factitious gods, see 1 Samuel 2:2;

according to all that we have heard with our ears; concerning what he did in the land of Egypt upon the Egyptians, and in the wilderness, in favour of the Israelites, and in the land of Canaan, by driving out the inhabitants before the people of Israel, and in the times of the judges, in raising them up to deliver his people.

Wherefore thou art great, O LORD God: for there is none like thee, neither is there any God beside thee, according to all that we have heard with our ears.

7:22 Great - Both in power and in goodness, as appears by the great and good things which thou hast done for me.

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.
