⁴⁶ he said to them, “Lay to heart all the words which I enjoin upon you this day, that you may command them to your children, that they may be careful to do all the words of this law. ⁴⁷ For it is no trifle for you, but it is your life, and thereby you shall live long in the land which you are going over the Jordan to possess.”
