Deuteronomy 30:16-18

Young's Literal Translation

¹⁶ in that I am commanding thee to-day to love Jehovah thy God, to walk in His ways, and to keep His commands, and His statutes, and His judgments; and thou hast lived and multiplied, and Jehovah thy God hath blessed thee in the land whither thou art going in to possess it.

¹⁷ `And if thy heart doth turn, and thou dost not hearken, and hast been driven away, and hast bowed thyself to other gods, and served them,

¹⁸ I have declared to you this day, that ye do certainly perish, ye do not prolong days on the ground which thou art passing over the Jordan to go in thither to possess it.
