Deuteronomy 4:1, 5, 40

“And now, O Israel, listen to the statutes and the rules that I am teaching you, and do them, that you may live, and go in and take possession of the land that the LORD, the God of your fathers, is giving you.

See, I have taught you statutes and rules, as the LORD my God commanded me, that you should do them in the land that you are entering to take possession of it.

Therefore you shall keep his statutes and his commandments, which I command you today, that it may go well with you and with your children after you, and that you may prolong your days in the land that the LORD your God is giving you for all time.”
