Deuteronomy 32:46-47 ▼

46 and he said to them, “Place in your heart all the words with which I am warning you today, which you shall command your sons to be careful to do, even all the words of this law.

47 For it is not an idle word for you; indeed it is your life. And by this word you will prolong your days in the land, which you are about to cross the Jordan to possess.”
