Deuteronomy 4:1-2

Now listen, Israel, listen carefully to the rules and regulations that I am teaching you to follow so that you may live and enter and take possession of the land that GOD, the God-of-Your-Fathers, is giving to you. Don’t add a word to what I command you, and don’t remove a word from it. Keep the commands of GOD, your God, that I am commanding you.
