Deuteronomy 32:47
Brenton's English Septuagint · Berean Standard Bible
For this [is] no vain word to you; for it [is] your life, and because of this word ye shall live long upon the land, into which ye go over Jordan to inherit it.
For they are not idle words to you, because they are your life, and by them you will live long in the land that you are crossing the Jordan to possess.”
