Deuteronomy 4:1, 5, 40

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.

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.

Keep his decrees and commands, which I am giving you today, so that it may go well with you and your children after you and that you may live long in the land the LORD your God gives you for all time.
