The Lord said to Moses: “Tell your brother Aaron that he is not to come whenever he chooses into the Most Holy Place behind the curtain in front of the atonement cover on the ark, or else he will die. For I will appear in the cloud over the atonement cover.
These are the commandments the Lord proclaimed in a loud voice to your whole assembly there on the mountain from out of the fire, the cloud and the deep darkness; and he added nothing more. Then he wrote them on two stone tablets and gave them to me.
