What does Leviticus 10:8 mean?

So they came near, and carried them in their coats out of the camp, as Moses had said.

Moses said to Aaron, and to Eleazar and to Ithamar, his sons, “Don’t let the hair of your heads go loose, and don’t tear your clothes; so that you don’t die, and so that he not be angry with all the congregation; but let your brothers, the whole house of Israel, bewail the burning which Yahweh has kindled.

You shall not go out from the door of the Tent of Meeting, lest you die; for the anointing oil of Yahweh is on you.” They did according to the word of Moses.

“You and your sons are not to drink wine or strong drink whenever you go into the Tent of Meeting, or you will die. This shall be a statute forever throughout your generations.

You are to make a distinction between the holy and the common, and between the unclean and the clean.

You are to teach the children of Israel all the statutes which Yahweh has spoken to them by Moses.”
