20And Moses said to the people, Have no fear: for God has come to put you to the test, so that fearing him you may be kept from sin.
21And the people kept their places far off, but Moses went near to the dark cloud where God was.
22And the Lord said to Moses, Say to the children of Israel, You yourselves have seen that my voice has come to you from heaven
23Gods of silver and gods of gold you are not to make for yourselves.
24Make for me an altar of earth, offering on it your burned offerings and your peace-offerings, your sheep and your oxen: in every place where I have put the memory of my name, I will come to you and give you my blessing.
25And if you make me an altar of stone do not make it of cut stones: for the touch of an instrument will make it unclean.
26And do not go up by steps to my altar, for fear that your bodies may be seen uncovered.
