1 Enoch 107

1 And I saw written on them that generation upon generation shall transgress, till a generation of righteousness arises, and transgression is destroyed and sin passes away from the earth, and all manner of good comes upon it.

2 And now, my son, go and make known to thy son Lamech that this son, which has been born, is in truth his son, and that this is no lie.

3 And when Methuselah had heard the words of his father Enoch--for he had shown to him everything in secret--he returned and showed them to him and called the name of that son Noah; for he will comfort the earth after all the destruction.
