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 Jordan to possess it.
Berean Study Bible (BSB) - Deuteronomy 32:47 >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.”
