Exodus 20:22-24

Living Bible

²² And the Lord told Moses to be his spokesman to the people of Israel. “You are witnesses to the fact that I have made known my will to you from heaven. ²³ Remember, you must not make or worship idols made of silver or gold or of anything else!

²⁴ “The altars you make for me must be simple altars of earth. Offer upon them your sacrifices to me—your burnt offerings and peace offerings of sheep and oxen. Build altars only where I tell you to, and I will come and bless you there.
