God said to Moses, "Give this Message to the People of Israel: 'You've experienced firsthand how I spoke with you from Heaven.
Don't make gods of silver and gods of gold and then set them alongside me.
Make me an earthen Altar. Sacrifice your Whole-Burnt-Offerings, your Peace-Offerings, your sheep, and your cattle on it. Every place where I cause my name to be honored in your worship, I'll be there myself and bless you.
If you use stones to make my Altar, don't use dressed stones. If you use a chisel on the stones you'll profane the Altar.
Don't use steps to climb to my Altar because that will expose your nakedness.'
