Deuteronomy 4:1-6 NIV
Now, Israel, hear the decrees and laws I am about to teach you. Follow them so that you may live and may go in and take possession of the land the LORD, the God of your ancestors, is giving you. Do not add to what I command you and do not subtract from it, but keep the commands of the LORD your God that I give you.
You saw with your own eyes what the LORD did at Baal Peor. The LORD your God destroyed from among you everyone who followed the Baal of Peor, but all of you who held fast to the LORD your God are still alive today.
See, I have taught you decrees and laws as the LORD my God commanded me, so that you may follow them in the land you are entering to take possession of it. Observe them carefully, for this will show your wisdom and understanding to the nations, who will hear about all these decrees and say, “Surely this great nation is a wise and understanding people.”
