Here we are shown the defiance of Esau. He surely must have known that God made a thumbs down sign against these people for their wickedness (Gen. 15: 16-21). He surely must have known about his grandfather's (Abraham) concern that his father (Isaac) should not be married to these women (Gen. 24:3) and yet here he shows his lack of interest in his family's special place and calling in God's program by marrying these Canaanites (the Hittites were one of the Canaanites).
Moses is showing his Israelite readers about Esau's attitude to God's covenant blessings promised to his fathers. He is not committed to it. Therefore the line of blessing is to go to Jacob.
