Exodus 20:22-24

Then the LORD said to Moses, “Thus you shall say to the children of Israel: ‘You have seen that I have talked with you from heaven. You shall not make anything to be with Me—gods of silver or gods of gold you shall not make for yourselves. An altar of earth you shall make for Me, and you shall sacrifice on it your burnt offerings and your peace offerings, your sheep and your oxen. In every place where I record My name I will come to you, and I will bless you.
