Genesis 9:18

And the sons of Noah, that went forth of the ark, were Shem, and Ham, and Japheth: and Ham is the father of Canaan.

The sons of Noah ... were Shem, and Ham, and Japheth (see the note at Gen. 9:32).

And Ham (is) the father of Canaan. The only conceivable reason why this fourth son of Ham is mentioned here in so particular a manner, was to show the Hebrews, for whose instruction, in the first instance, this history was written, that the race who were in possession of the land on which they were about to enter as their promised inheritance, had been accursed from the days of their father.
