(22) All that we have heard with our ears.--Such expressions are common enough in all languages not only for that which has been communicated orally, but for all that has been made known in any way; the same word is used with reference to written records in Deuteronomy 4:6; 2Kings 17:14; 2Kings 18:12; 2Kings 19:16 (in Hezekiah's prayer in reference to Sennacherib's letter); Nehemiah 9:29; probably Esther 2:8; and in many other places. (So also the corresponding Greek word, Revelation 1:3, &c). It is therefore entirely unnecessary to suppose that David refers here only to oral tradition; he means the history of the Divine dealings with his people as recorded in their sacred books.

Verse 22. - Wherefore thou art great. God's goodness is to David a proof of his greatness, and he sees it displayed, not only in his dealings with himself, but also in the past history of the Jewish nation. There is in this a depth of evangelic piety. An unconverted heart would see the greatness of God in the majesty of creation, or in severe dealings with the impenitent. David saw it in acts of mercy and kindness. We look upon Elijah as the very type of sternness, yet he too recognized the presence of God in "the still small voice" of gentleness and love (1 Kings 19:13).

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.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.
