And Cain went out from the presence of the Lord, and dwelt on the east of Eden — Somewhere distant from the place were Adam and his religious family resided: distinguishing himself and his accursed generation from the holy seed; in the land of Nod — That is, of shaking or trembling, because of the continual restlessness of his spirit. Those that depart from God cannot find rest any where else. When Cain went out from the presence of the Lord, he never rested after.
