Exodus 20:20-26

Moses said to the people, “Do not be afraid. God has come to test you, so that the fear of God will be with you to keep you from sinning.” The people remained at a distance, while Moses approached the thick darkness where God was. Then the LORD said to Moses, “Tell the Israelites this: ‘You have seen for yourselves that I have spoken to you from heaven: Do not make any gods to be alongside me; do not make for yourselves gods of silver or gods of gold. “ ‘Make an altar of earth for me and sacrifice on it your burnt offerings and fellowship offerings, your sheep and goats and your cattle. Wherever I cause my name to be honored, I will come to you and bless you. If you make an altar of stones for me, do not build it with dressed stones, for you will defile it if you use a tool on it. And do not go up to my altar on steps, or your private parts may be exposed.’
