Deuteronomy 4:1-2

“Now, O Israel, listen to the statutes and the judgments which I am teaching you to perform, so that you may live and go in and take possession of the land which the LORD, the God of your fathers, is giving you. You shall not add to the word which I am commanding you, nor take away from it, that you may keep the commandments of the LORD your God which I command you.
