What does Genesis 28:6 mean?

Esau realized that Isaac had blessed Jacob and sent him away to Paddan-Aram to find a wife, and that when he blessed Jacob, he told him not to marry a Canaanite woman. Genesis 28:6 - Modern Text Bible

(Esau notices that his father is serious about Jacob marrying within the family and not from the local Canaanite people. Esau is paying attention to what his parents value.)
