2 BARUCH 57
57:1 And after these you saw the bright waters; that is the fountain of Abraham and his generation, and the coming of his son, and the son of his son, and of those who are like them.
57:2 For at that time the unwritten Torah was in force among them, and the works of the commandments were accomplished at that time, and the belief in the coming judgment was brought about, and the hope of the world which will be renewed was built at that time, and the promise of the Life that will come later was planted.
57:3 Those are the bright waters which you have seen.
