The book of Psalms contains new doctrine after the law which was given by Moses; and thus it is the second book of doctrine after the Scripture of Moses. After the death, then of Moses and Joshua, and after the judges, David arose, one deemed worthy to be called the father of the Saviour, and he was the first to give the Hebrews a new style of psalmody, by which he did away with the ordinances established by Moses with respect to sacrifice, and introduced a new mode of the worship of God by hymns and acclamations; and many other things also beyond the law of Moses he taught through his whole ministry. And this is the sacredness of the book, and its utility. And the account to be given of its inscription is this: (for) as most of the brethren who believe in Christ think that this book is David's, and inscribe it "Psalms of David," we must state what has reached us with respect to it. The Hebrews give the book the title "Sephra Thelim," ¹ and in the "Acts of the Apostles" it is called the "Book of Psalms" (the words are these, "as it is written in the Book of Psalms"), but the name (of the author) in the inscription of the book is not found there. And the reason of that is, that the words written there are not the words of one man, but those of several together; Esdra, as tradition says, having collected in one volume, after the captivity, the psalms of several, or rather their words, as they are not all psalms. Thus the name of David is prefixed in the case of some, and that of Solomon in others, and that of Asaph in others. There are some also that belong to Idithum (Jeduthun); and besides these there are others that belong to the sons of Core (Korah), and even to Moses. As they are therefore the words of so many thus collected together, they could not be said by any one who understands the matter to be by David alone.
