Deuteronomy 4:1-4

1Now, Israel, pay attention to the statutes and ordinances I am about to teach you, so that you might live and go on to enter and take possession of the land that the Lord, the God of your ancestors, is giving you.

2Do not add a thing to what I command you nor subtract from it, so that you may keep the commandments of the Lord your God that I am delivering to you.

3You have witnessed what the Lord did at Baal Peor, how he eradicated from your midst everyone who followed Baal Peor.

4But you who remained faithful to the Lord your God are still alive to this very day, every one of you.
