Deuteronomy 32:44-47

Moses spoke the words of the song so that all the Israelites could hear, and Joshua helped him. When Moses had finished, he said, “Always remember this song I have taught you today. And let it be a warning that you must teach your children to obey everything written in The Book of God's Law . The Law isn't empty words. It can give you a long life in the land that you are going to take.”
