Two of Aaron’s sons, Nadab and Abihu, offered God some “unauthorized” fire. God didn’t like that, so he set them on fire and killed them. Moses got a couple of their cousins, Mishael and Elzaphan, to carry the dead guys out of the tent. Then he told Aaron’s other sons, Eleasar and Ithamar, not to tear their clothes or wear their hair loose or they would die. Then he told them if they left the tent they would die.

Moses told Eleazar and Ithamar to take the grain offering and eat it (unleavened!) beside the altar. Then he got mad at them for not eating a goat or something.
