(19) Is this the manner of man?--This clause is very obscure in the original, and little help in determining its meaning can be had from the ancient versions. The word translated "manner" is a very common one, and never has this sense elsewhere; its well established meaning is law. Neither is there any reason to suppose that a question is intended. Translate, "And this is a law for man!" David expresses his surprise that so great a promise, even a decree of an eternal kingdom, should be given to such as himself and his posterity. The same thought is far less strikingly expressed in the parallel passage (1Chronicles 17:18), "Thou hast regarded me according to the estate of a man of high degree."

Verse 19. - And is this the manner of man, O Lord God? Hebrew, and this is the law of man, O Lord Jehovah. In the parallel passage (1 Chronicles 17:17) the Hebrew has, "And thou hast regarded me according to the law of a man of high degree." The rendering of the Authorized Version here, which, by making the clause interrogative, implies a negative, gives absolutely no sense; but some commentators render, "And this is the manner of men, O Lord Jehovah," understanding thereby that God was acting towards David in a human manner, that is, as an earthly friend and benefactor would do. But though the Revised Version favours this rendering, the Hebrew word torah never has this meaning, and, unless, the attempt be made to amend the text, for which the versions give no help, we must take torah in its usual sense, and understand that this continuance of David's house into the distant future has now become a human law, that is, a divinely constituted ordinance, which must now take its place among the laws which govern human affairs. The words are undoubtedly difficult, and we feel that David was speaking in an ejaculatory manner, in sentences but half expressed, breaking forth from him bit by bit, under the pressure of deep excitement within. We notice too that, while there is no direct reference to the Messiah in David's words, yet that the Psalms indicate that he did connect the duration of his house with the Messiah's advent; and this ejaculation may have sprung forth, if not from a fully formed conviction, yet from the feeling that the permanence of his house was for the purpose of a higher kingdom than that of Jerusalem; and so the promise was a "law of man" and the promulgation of a decree which affected the whole human race. This may be the meaning of the Vulgate, which renders "a law of Adam," that is, one embracing within its scope all Adam's race,

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.And this was yet a small thing in thy sight, O Lord God,.... This of raising him to the throne, and settling him on it, was but a small thing in comparison of what he promised to do for him and his:

but thou hast spoken also of thy servant's house for a great while to come; since he had not only spoken of a son that should succeed him in the kingdom, but that he would make him an house, and establish his kingdom; yea, that the throne of his kingdom should be established for ever, that a race of kings should spring from him, and especially the King Messiah, of whose kingdom there would be no end; and so the Targum,"thou hast spoken of the house of thy servant unto the world to come,''a phrase often used by the Jews for the times of the Messiah; see Hebrews 2:5; and so Abarbinel thinks this clause has respect to Messiah the son of David:

and is this the manner of man, O Lord God? to bestow their favours on their inferiors, persons of no worth and merit, and is a profuse manner? it is not; and yet to one so much below thee, and so undeserving, hast thou most largely and liberally given such great and unmerited mercies: or is it the manner, or customary to deal thus with men mean and abject, though it may with great personages that make a great figure in the world? it is not: and yet I am regarded by thee as if I was one of the greatest monarchs on earth: this sense agrees with the parallel text in 1 Chronicles 17:17; "and hast regarded me according to the estate of a man of high degree"; or, "this is the law", or "doctrine of the man who is the Lord God" (c). This doctrine contained in the promise now made respects the seed of the woman, the promised Shiloh, the illustrious man, Jehovah's fellow, the incarnate God, the Messiah, who is Jehovah our righteousness, the true God and eternal life.
