Who wrote about Noah and his sons?

Answer 1

Moses is credited with being the author of Genesis and thus of the account of Noah and his family. The internal evidence, historical continuity of recognition amongst the Jews, and the absence of plausible alternatives all support this.

Answer 2

We can read about Noah and his sons in the Book of Genesis, where there are actually two biblical stories of Noah and his sons being saved from the Flood. They are so cleverly woven together as to appear just one, slightly complicated story. When Genesis was being redacted, the followers of each story were not willing to give up their special story, so both were included. One clear example is in Genesis 6:19-20, where Noah is told to take two of every animal onto the Ark, and in Genesis 7:1, where he is told to take two of every unclean animal, but seven of every clean animal. Similarly, one story has the flood subsiding in just forty days, while the other says that it lasted one year.

The two different authors of the biblical stories of Noah are called the Priestly source and the Yahwist. The Flood verses attributed to the Priestly author are: Genesis 6:9-22, 7:6, 7:8-9, 7:11, 7:13-16a, 7:18-21, 7:24, 8:1-2a, 8:3b-5, 8:7, 8:13a, 8:14-19, 9:1-17. The verses attributed to the Yahwist are: Genesis 6:5-8, 7:1-5, 7:7, 7:10, 7:12, 7:16b-17, 7:22-23, 8:2b-3a, 8:6, 8:8-12, 8:13b, 8:20-22.

Answer 3

Narratives of the Flood were preserved in writing among tens of ancient nations all over the Earth, since it was an actual event and a global one.

These narratives were garbled with a hodgepodge of warring deities and other idolatrous drivel; and it was only among the ancient Hebrews that the original, moralistic text was retained.

Even before Moses, the Israelites had parchments on which their early traditions were recorded (midrash Shemot Rabbah 5:18) which they studied regularly (ibid). These included the entire book of Genesis (ibid. 5:22), which had been prophetically written by the Forefathers themselves.

Tradition states that Moses wrote a scroll containing the text of Genesis, at God's command, before the formal Giving of the Torah (Rashi commentary, Exodus ch.24). It was this scroll which he read to the Israelites (Exodus 24:7) as an introduction to what God's covenant would entail.
The words of this scroll were soon incorporated in the complete Torah itself by God, and the Torah as we have it today was written to completion by Moses shortly before he died (Deuteronomy 31:24).
No Hebrew copy of the Torah has ever been found to differ with the others, worldwide. The Torah we possess today contains the exact wording written by Moses. Hypotheses which claim multiple authors for the Torah are based upon zero physical evidence.See also the Related Links.
