Then the LORD said to Moses, "Here is what you must tell the people of Israel. Say to them, 'You have seen for yourselves what I said to you from heaven.
Do not put any other gods in place of me. Do not make silver or gold statues of them for yourselves.
" 'Make an altar out of dirt for me. Sacrifice your burnt offerings and friendship offerings on it. Sacrifice your sheep, goats and cattle on it. I will come to you and bless you everywhere I cause my name to be honored.
" 'If you make an altar out of stones in honor of me, do not build it with blocks of stone. You will make it "unclean" if you use a tool on it.
" 'Do not walk up steps to my altar. If you do, someone might see your naked body under your robes.'
