Deuteronomy 4:1-2

Now, Israel, in light of all that, listen to the regulations and the case laws that I am teaching you to follow, so that you may live, enter, and possess the land that the LORD, your ancestors’ God, is giving to you. Don’t add anything to the word that I am commanding you, and don’t take anything away from it. Instead, keep the commands of the LORD your God that I am commanding all of you.
