And Ham, the father of Canaan, saw the nakedness of his father, and told his two brethren outside.
All Commentaries on Genesis 9:22 Go To Genesis 9
Ambrose of Milan
AD 397
When we read that he was blessed who was blessed by his father and that he was cursed who was cursed by his father, we learn above all else what great reverence to show our parents. And God gave this privilege to parents so as to arouse respect in the children. The formation of the children is, then, the prerogative of the parents. Therefore honor your father that he may bless you.
