Thematic Bible: What is not vain

When Moses had finished speaking all these words to all Israel, he said to them, "Take to your heart all the words with which I am warning you today, which you shall command your sons to observe carefully, even all the words of this law. "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."
