Deuteronomy 4:1-2

New Revised Standard Version, Anglicised Catholic Edition

Moses Commands Obedience

4 So now, Israel, give heed to the statutes and ordinances that I am teaching you to observe, so that you may live to enter and occupy the land that the Lord, the God of your ancestors, is giving you. ² You must neither add anything to what I command you nor take away anything from it, but keep the commandments of the Lord your God with which I am charging you.
