Deuteronomy 4:1-2

¹“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. ²You 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.
