This tradition, which was commonly accepted until the time of the Reformation, dates from the first Christian century, for it is found in the fourth book of Ezra (xiv. 44): It is there said that Ezra was inspired to dictate to five men, during forty days, ninety-four books, of which twenty-four (the canonical books) were to be published. The tradition is repeated quite frequently by the Fathers, but that Ezra formed the Old Testament canon is impossible, for some of the books were not written until after his day. The truth is, it was a gradual growth and was not completed until the second century b.c. See above, Bk. III. chap. 10, note 1.
