Deuteronomy 32:45-47

21st Century King James Version

⁴⁵ And Moses made an end of speaking all these words to all Israel,

⁴⁶ and he said unto them: “Set your hearts unto all the words which I testify among you this day, which ye shall command your children to observe to do, all the words of this law.

⁴⁷ For it is not a vain thing for you, because it is your life; and through this thing ye shall prolong your days in the land whither ye go over the Jordan to possess it.”
