2 Samuel 22:1 - David's Psalm Of Thanksgiving.

David spake. The introduction was probably written by the prophet who compiled the Books of Samuel. The scribe who collected the Book of Psalms would be a priest, and he has repeated it with one or two additions, the most important of which is that the psalm was written "by David the servant of Jehovah." This title; meaning the minister or vicegerent of Jehovah, is one so high that it would certainly not have been given to David in his lifetime; nor was it even until Moses was dead that he was honoured with this rank ( Deuteronomy 34:5 ). But what was David's right to this title, which put him on a level with Moses? It was this: In adding to the sacrificial ritual enacted by Moses a daily service in the temple of sacred minstrelsy and songs, David was acting with higher powers than were ever exercised by any other person. For though, as we have seen, Samuel was the originator of these services in his schools, yet. there is a wide difference between private and public services; and David made his anthems part of the national liturgy. But it would only be when the halo of long use had gathered round his holy psalmody that David would be placed on in equality with Moses, and his authority a institute a new ritual for the nation be recognized.
