Thematic Bible: What is not vain

And when Moses had finished speaking all these words to all Israel, he said to them, "Take to heart all the words by which I am warning you today, that you may command them to your children, that they may be careful to do all the words of this law. For it is no empty word for you, but your very life, and by this word you shall live long in the land that you are going over the Jordan to possess."
