Genesis 9:24

And Noach awoke from his wine, and knew, by the relation of a dream, what had been done to him by Cham his son, who was inferior in worth, on the account that he had not begotten a fourth son.

ויקץ נח, drunkenness makes a person as insensitive to what goes on around him as does sleep. Therefore, the Torah describes his becoming sober as “waking up.”

ויקץ, the reason why this is spelled with a single letter י so that the letter י which is part of the root is missing, is because this was not a true “awakening:” from sleep. [The fact is that in all the Torah scrolls nowadays the word is spelled with two letters י, so that there is no need to justify a “missing” letter, seeing it is not missing. Ed.]

אשר עשה לו בנו הקטן, if we were to understand these words as referring to what Cham had done, we would have to understand the word הקטן as “the inferior one.” We have explained already on 5,32 as well as on 6,10 that Cham was not the youngest of Noach’s sons as he was never mentioned last in the list of Noach’s sons. If what he did was to only tell his brothers about his father’s nakedness instead of first covering up his private parts, why did Noach cause Canaan, Cham’s son, instead of Cham himself? He foresaw in prophetic vision that both Cham and his offspring would forever be evil people. Actually, he could not effectively curse Cham, as G’d had already blessed him. (compare verse 1 in our chapter) Our sages (Bereshit Rabbah 36,7) therefore say that “Cham saw and Canaan was cursed,” the reason being that once G’d has blessed someone, man cannot annul G’d’s blessing. Other sages are of the opinion that Canaan castrated Noach, and that the words בנו הקטן refer to Canaan, seeing that he was the youngest of Cham’s sons. There is nothing unusual in a grandson being referred to as a “son.”
