Nadab and Abihu, for offering of strange fire, are burnt by fire.
Leviticus 10:1 And Nadab and Abihu, the sons of Aaron, took each of them his censer, and put fire therein, and laid incense thereon, and offered strange fire before the LORD, which he had not commanded them. Leviticus 10:2 And there came forth fire from before the LORD, and devoured them, and they died before the LORD. Leviticus 10:3 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. Leviticus 10:4 And Moses called Mishael and Elzaphan, the sons of Uzziel the uncle of Aaron, and said unto them, Draw near, carry your brethren from before the sanctuary out of the camp. Leviticus 10:5 So they drew near, and carried them in their coats out of the camp; as Moses had said.
Aaron and his sons are forbidden to mourn for them.
Leviticus 10:6 And Moses said unto Aaron, and unto Eleazar and unto Ithamar, his sons, Let not the hair of your heads go loose, neither rend your clothes; that ye die not, and that he be not wroth with all the congregation: but let your brethren, the whole house of Israel, bewail the burning which the LORD hath kindled. Leviticus 10:7 And ye shall not go out from the door of the tent of meeting, lest ye die: for the anointing oil of the LORD is upon you. And they did according to the word of Moses.
The priests are forbidden wine when they are to go into the Tabernacle.
Leviticus 10:8 And the LORD spake unto Aaron, saying, Leviticus 10:9 Drink no wine nor strong drink, thou, nor thy sons with thee, when ye go into the tent of meeting, that ye die not: it shall be a statute for ever throughout your generations: Leviticus 10:10 and that ye may put difference between the holy and the common, and between the unclean and the clean; Leviticus 10:11 and that ye may teach the children of Israel all the statutes which the LORD hath spoken unto them by the hand of Moses.
The law of eating the holy things.
Leviticus 10:12 And Moses spake unto Aaron, and unto Eleazar and unto Ithamar, his sons that were left, Take the meal 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: Leviticus 10:13 and ye shall eat it in a holy place, because it is thy due, and thy sons' due, of the offerings of the LORD made by fire: for so I am commanded. Leviticus 10:14 And the wave breast and the heave thigh shall ye eat in a clean place; thou, and thy sons, and thy daughters with thee: for they are given as thy due, and thy sons' due, out of the sacrifices of the peace offerings of the children of Israel. Leviticus 10:15 The heave thigh 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, as a due for ever; as the LORD hath commanded.
Aaron's excuse for transgressing thereof.
Leviticus 10:16 And Moses diligently sought the goat of the sin offering, and, behold, it was burnt: and he was angry with Eleazar and with Ithamar, the sons of Aaron that were left, saying, Leviticus 10:17 Wherefore have ye not eaten the sin offering in the place of the sanctuary, seeing it is most holy, and he hath given it you to bear the iniquity of the congregation, to make atonement for them before the LORD? Leviticus 10:18 Behold, the blood of it was not brought into the sanctuary within: ye should certainly have eaten it in the sanctuary, as I commanded. Leviticus 10:19 And Aaron spake unto Moses, Behold, this day have they offered their sin offering and their burnt offering before the LORD; and there have befallen me such things as these: and if I had eaten the sin offering today, would it have been well-pleasing in the sight of the LORD? Leviticus 10:20 And when Moses heard [that], it was well-pleasing in his sight.
