Development of The Hebrew Bible Canon - 2 Esdras

2 Esdras

The first reference to a 24-book Jewish canon is found in 2 Esdras 14:45–46, which was probably written in the first half of the 2nd century CE:

Make public the twenty-four books that you wrote first, and let the worthy and the unworthy read them; but keep the seventy that were written last, in order to give them to the wise among your people. —RSV
