It is not written that Canaan committed incestuous.
It is written that Ham who committed the incestuous.
No, it is not. Ham isn't even blamed or cursed for any crime/sin.
When Ham saw the nakedness of Noah (his father).
That isn't a sdin. Uncovering it is the sin.
GENESIS 9:22
22 And Ham, the father of Canaan, saw the nakedness of his father, and told his two brethren without.
Since God is Speaking in Parable. The revelation of God, Ham slept with his mother.
No, it was Canaan. Only Canaan is punished/cursed.
LEVITICUS 18:6-7
7 The nakedness of thy father, or the nakedness of thy mother, shalt thou not uncover: she is thy mother; thou shalt not uncover her nakedness.
8 The nakedness of thy father's wife shalt thou not uncover: it is thy father's nakedness.
Perhaps you are confuse. Ham is the Son of Noah and not Canaan is the Son of Noah.
No, you are confused. The Hebrew word for son can also mean grandson. I have studied this in the Hebrew language, not only in English.
