Jamieson, Fausset and Brown on Genesis 33:12

Ge 33:12-20. The Parting.

12. And he said, Let us take our journey--Esau proposed to accompany Jacob and his family through the country, both as a mark of friendship and as an escort to guard them. But the proposal was prudently declined. Jacob did not need any worldly state or equipage. Notwithstanding the present cordiality, the brothers were so different in spirit, character, and habits--the one so much a man of the world, and the other a man of God, that there was great risk of something occurring to disturb the harmony. Jacob having alleged a very reasonable excuse for the tardiness of his movements, the brothers parted in peace.
