unfit altar

The People Are Afraid
(Deuteronomy 5.23-33)

18 The people trembled with fear when they heard the thunder and the trumpet and saw the lightning and the smoke coming from the mountain. They stood a long way off 19 and said to Moses, “If you speak to us, we will listen. But don't let God speak to us, or we will die!”

20 “Don't be afraid!” Moses replied. “God has come only to test you, so that by obeying him you won't sin.” 21 But when Moses went near the thick cloud where God was, the people stayed a long way off.
Idols and Altars

22 The Lord told Moses to say to the people of Israel:

With your own eyes you saw me speak to you from heaven. 23 So you must never make idols of silver or gold to worship in place of me.[b]

24 Build an altar out of earth, and offer on it your sacrifices[c] of sheep, goats, and cattle. Wherever I choose to be worshiped, I will come down to bless you. 25 If you ever build an altar for me out of stones, do not use any tools to chisel the stones, because that would make the altar unfit for use in worship. 26 And don't build an altar that requires steps; you might expose yourself when you climb up.
