Which book of the Bible has Noah's grandson committing homosexuality?

Answer 1

It is found in Genesis 9:20-25 and is confusing for many. Just whom did Noah curse - Ham, or Ham's youngest son Canaan (Noah's grandson)? Consider the following from a Hebrew scholar Tayler Lewis:

"The Hebrew rendered 'his younger son,' cannot refer to Ham, who was older than Japheth, but means the least or youngest of the family, and hence is descriptive of Canaan. The words, 'had done unto him' means something very shameful had been done to the old man in his unconscious state, and of such a nature that it becomes manifest to him immediately on his recovery...

"Thus regarded, everything seems to point to some wanton act done by the very one who is immediately named in the severe malediction that follows: 'Cursed be Canaan.' He was the youngest son of Ham, as he was also the youngest son of Noah, according to the well-established Semitic peculiarity by which all the descendants are alike called sons" (Lange's Commentary on the Holy Scriptures: Genesis, p. 338).

Jewish answer:

No book of The Bible has Noah's grandson committing a homosexual act. At least not explicitly. All that is stated is "And Ham, the father of Canaan, saw the nakedness of his father, and told his two brothers outside...And Noah awoke from his wine, and knew what his youngest son had done to him."

The reason why Noah didn't curse Ham is because God Himself had blessed Noah and his three sons (Gen. ch.9). And the reason why Ham is called the youngest is because it is meant (here) to mean "the least worthy" (Rashi commentary).

Canaaan deserved to be cursed because it was he who told Ham of Noah's nakedness (midrash Gen. Rabbah 36:7).

Though the verses don't say it outright, the sages of the Talmud do indeed state the tradition that Ham raped Noah. Another opinion is that he castrated him (Talmud, Sanhedrin 70a).
