Leviticus10


Nadab and Abihu do not obey God.


Aaron's sons were named Nadab and Abihu. They put fire in their firepans. They burned some incense and offered it to God. But God had not told them to do this. God sent fire and burned up Nadab and Abihu. They both died.
[1] And Nadab and Abihu, the sons of Aaron, took either of them his censer, and put fire therein, and put incense thereon, and offered strange fire before the LORD, which he commanded them not.
[2] And there went out fire from the LORD, and devoured them, and they died before the LORD.


Moses talked to Aaron.  Moses told Aaron what God said.  God said that the people who come near Him (the priests) should see that He is holy. Then all of the people will see His glory. Aaron did not say anything. 
[3] Then Moses said unto Aaron, This is it that the LORD spake, saying, I will be sanctified in them that come nigh me, and before all the people I will be glorified. And Aaron held his peace.


Aaron's brother was Uzziel. Uzziel had 2 sons named Mishael and Elzaphan. Moses called Mishael and Elzaphan and told them to carry the bodies of Nadab and Abihu out of the camp.
[4] And Moses called Mishael and Elzaphan, the sons of Uzziel the uncle of Aaron, and said unto them, Come near, carry your brethren from before the sanctuary out of the camp.


Mishael and Elzaphan obeyed. They pulled on Nadab's and Abihu's clothes and dragged them out of the camp.
[5] So they went near, and carried them in their coats out of the camp; as Moses had said.


Moses talked to Aaron and his 2 other sons, Eleazar and Ithamar.  He told them not to feel sad and mourn for Nadab and Abihu. They were not allowed to do the things that Israelite people usually did when they mourn--ripping their clothes and messing up their hair.  If they mourned and did these things, they would die, too, and God would punish all of the Israelites.  But Aaron's other family members and the other Israelites were allowed to mourn for Nadab and Abihu.
[6] And Moses said unto Aaron, and unto Eleazar and unto Ithamar, his sons, Uncover not your heads, neither rend your clothes; lest ye die, and lest wrath come upon all the people: but let your brethren, the whole house of Israel, bewail the burning which the LORD hath kindled.


Aaron and his sons should not leave the tabernacle because they had been anointed with oil and were priests.  If they left the tabernacle, they would die.  They obeyed God and did what Moses told them to do. 
[7] And ye shall not go out from the door of the tabernacle of the congregation, lest ye die: for the anointing oil of the LORD is upon you. And they did according to the word of Moses.


God talked to Aaron.  He told him that he and his sons should not drink wine or strong drink before they went into the tabernacle. If they did drink these and then went into the tabernacle, they would die.  This would be a law forever. 
[8] And the LORD spake unto Aaron, saying,
[9] Do not drink wine nor strong drink, thou, nor thy sons with thee, when ye go into the tabernacle of the congregation, lest ye die: it shall be a statute for ever throughout your generations:


They must know the difference between holy and unholy (not holy) and between clean and unclean (not clean).  They must teach all of the Israelites so that the Israelites would learn the laws that God told Moses to tell them.
[10] And that ye may put difference between holy and unholy, and between unclean and clean;
[11] And that ye may teach the children of Israel all the statutes which the LORD hath spoken unto them by the hand of Moses.


Moses talked to Aaron and his sons. He told them to take the grain offering that was leftover. They should eat it without any leavening (yeast) beside the altar. It is very holy. They should eat it in the holy place. It is their part of the offerings made to God.  This is what God told Moses that they should do. 
[12] And Moses spake unto Aaron, and unto Eleazar and unto Ithamar, his sons that were left, Take the meat offering that remaineth of the offerings of the LORD made by fire, and eat it without leaven beside the altar: for it is most holy:
[13] And ye shall eat it in the holy place, because it is thy due, and thy sons' due, of the sacrifices of the LORD made by fire: for so I am commanded.


Aaron and his sons and his daughters could eat the breast meat and shoulder from the wave offering and the heave offering. They should eat them in a holy place.   It is their part of the peace offerings that the Israelites made to God. They would be allowed to eat these offerings forever.
[14] And the wave breast and heave shoulder shall ye eat in a clean place; thou, and thy sons, and thy daughters with thee: for they be thy due, and thy sons' due, which are given out of the sacrifices of peace offerings of the children of Israel.
[15] The heave shoulder and the wave breast shall they bring with the offerings made by fire of the fat, to wave it for a wave offering before the LORD; and it shall be thine, and thy sons' with thee, by a statute for ever; as the LORD hath commanded.


Moses asked about the goat that was the sin offering.  He learned that it had been burned on the altar. Moses was mad at Aaron's sons, Eleazar and Ithamar.   They were supposed to eat the goat. When the priests ate sacrifices, the priests became holy. When the priests were holy, they could make the offerings to take away the sins of the other Israelites. 
[16] And Moses diligently sought the goat of the sin offering, and, behold, it was burnt: and he was angry with Eleazar and Ithamar, the sons of Aaron which were left alive, saying,
[17] Wherefore have ye not eaten the sin offering in the holy place, seeing it is most holy, and God hath given it you to bear the iniquity of the congregation, to make atonement for them before the LORD?


The goat's blood was not taken into the tent.  That meant that they were supposed to eat the meat in a holy place.  That is what Moses had told them to do. 
[18] Behold, the blood of it was not brought in within the holy place: ye should indeed have eaten it in the holy place, as I commanded.
