Leviticus 10:1-7 Aaron’s sons offered an unauthorized offering to the Lord and the Lord killed them. Moses tells Aaron that Lord must be sanctified and glorified. What Aaron’s sons did was wrong and their death was justified. Moses had Aaron’s relatives carry away the bodies. Aaron’s other two sons, Eleazar and Ithamar were instructed to not let their hair hang loose or tear their clothes (Not to mourn) or death will come to them and wrath to the congregation. They were to bewail the burning the Lord kindled and not go outside the tent of meeting or they would die, for they were anointed.
Leviticus 10:8-11 The Lord told Aaron that they were not allowed to drink wine nor strong drink and then enter the tent of meeting or they will die. They must be Holy.
Leviticus 10:12-15 The Lord repeats the offerings to Aaron’s other two sons that replaced Nadab and Abihu.
Leviticus 10:16-20 Moses inspected the goat offering. It was all burned up, for Eleazar and Ithamar should have eaten the offering. The blood of the goat wasn’t brought into the sanctuary. Aaron argued with Moses that they couldn’t eat for being still very upset upon what happened to his Nadab and Abihu. Aaron was wrong, but Moses dropped the issue for he did sympathize with Aaron’s grief.
