Deuteronomy 30:17-20

But if thy heart turn away, and thou wilt not hear, but shalt be drawn away, and worship other gods, and serve them; I denounce unto you this day, that ye shall surely perish; ye shall not prolong your days in the land, whither thou passest over the Jordan to go in to possess it. I call heaven and earth to witness against you this day, that I have set before thee life and death, the blessing and the curse: therefore choose life, that thou mayest live, thou and thy seed; to love Jehovah thy God, to obey his voice, and to cleave unto him; for he is thy life, and the length of thy days; that thou mayest dwell in the land which Jehovah sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give them.
