Hebrews 11:15

15. Mindful of that country If the emigrating Abraham had dropped his faith, and given up the promises as to Canaan, he could have gone back to Chaldea at any chosen time. He would then have resigned the future earthly Jerusalem, the foundership of the Old Testament dispensation, and the fatherhood of the Messiah. He and his might have gone into the idolatry of the Chaldeans and have been forgotten.
