2 Kings 17:35-39

17:35 The Lord made an agreement with them and instructed them, “You must not worship other gods. Do not bow down to them, serve them, or offer sacrifices to them. 17:36 Instead you must worship the Lord, who brought you up from the land of Egypt by his great power and military ability; bow down to him and offer sacrifices to him. 17:37 You must carefully obey at all times the rules, regulations, law, and commandments he wrote down for you. You must not worship other gods. 17:38 You must never forget the agreement I made with you, and you must not worship other gods. 17:39 Instead you must worship the Lord your God; then he will rescue you from the power of all your enemies.”
