[Sidenote: Canonization of the Psalter and Lamentations]
The Psalter doubtless passed through different stages of canonization, as did the Old Testament itself. The earliest collection was, in the beginning, probably made for liturgical purposes, and its adoption in the service of the temple was practically equivalent to canonization. When successive collections were added, they too were thus canonized. The result was that the Psalter, when complete, enjoyed a position somewhat similar to that of the Law and the Prophets, although the authority of each rested upon a different basis. That the Psalter was early canonized is further demonstrated by a quotation in I Maccabees vii. 17 (about 125 B.C.) from Psalm lxxix. 2, 3, introduced by the words, as it is written in the Scriptures. This conclusion is also supported by the significant reference in the New Testament to the Law, the Prophets, and the Psalms (Lk. xxiv. 44). Jesus' use of the Psalter indicates that in his day its canonicity was already thoroughly established. Lamentations, by a late tradition attributed to Jeremiah, was probably also canonized contemporaneously with the Psalms.

The canonization of the book of Proverbs, like that of the Psalter, was undoubtedly by successive stages. The Jews of the Greek and Maccabean period were especially appreciative of this type of literature, and it was doubtless accorded its position of authority primarily because it rang true to human experience. That it was attributed to Solomon also told in its favor. Ben Sira's indirect testimony suggests that it and the books of Chronicles, Ezra, and Nehemiah, which were in close accord with the point of view of later Judaism, were already in his day associated with the Law and the Prophets. The book of Ruth was probably at this time added to the other historical books.
[Sidenote: Canonization of the book of Daniel]
The absence of any reference in Ben Sira to Daniel is significant. The first allusion to it comes from the last half of the second century before Christ. First Maccabees i. 54 appears to quote the prediction of Daniel ix. 27, and in I Maccabees ii. 59, 60, Daniel and his three friends are held up as noble examples of virtue. Thus it would seem that within a half century after the book of Daniel was written its authority was recognized. In New Testament times its canonicity is fully established (e.g., cf. I Cor. vi. 2, and Dan. vii. 22).
[Sidenote: Date of the completion of the Hebrew Old Testament canon]
Concerning the canonicity of two books, Ecclesiastes and the Song of Songs or Canticles, the opinions of the rabbis continued to differ until the close of the first Christian century. From the Mishna we learn that the school of Shammai accepted Ecclesiastes, while that of Hillel rejected it. Finally, in a conference in Jamnia, about 100 A.D., the two schools finally agreed to accept both books as canonical. From Second Esdras and Josephus, however, we learn that the present Hebrew and Protestant canon of the Old Testament had already for some time been practically adopted by common consent.
[Sidenote: Contents of the last group of writings]
The last collection, which includes eleven books known as the Hagiographa or Sacred Writings, constitutes the third general division of the Hebrew Scriptures. It is a heterogeneous group of histories, prophecies, stories, and wisdom books. Some, like the Psalter, were, as we have seen, probably canonized as early as the Prophets; although the final canon of the Old Testament was not closed until 100 A.D. Even later the canonicity of Ecclesiastes, the Song of Songs, and Esther was sometimes questioned; most of them were regarded as authoritative as early as 100 B.C. Here, as in the case of the New Testament, the real decision was not the work of any school or council; but gradually, on the basis of their intrinsic merit, the twenty-four books of the Hebrew Bible were singled out of a much larger literature and recognized, at least by the Jews of Palestine, as the authoritative record of God's revelation through their race.
