What is the "strange fire" that Nadab and Abihu offered before the Lord?

“Strange fire” means fire God had not told them to use in worship. The fire for incense was supposed to come from the altar God had lit, showing that worship starts with what He provides, not with human ideas. Nadab and Abihu used common fire and acted on their own, not according to God’s command. Their offering might have looked religious, but it was not obedient. This shows that in God’s sight, worship is not just about outward form or zeal, but about listening carefully to what He has said.

Why did God send fire to kill Nadab and Abihu so suddenly?

God sent fire to kill Nadab and Abihu to show how holy He is and how serious it is to twist His worship. They were priests, very close to the altar, and had just been set apart for service, yet they ignored His clear instructions. God said, “I will be sanctified in them that come nigh me,” meaning He will be treated as holy by those who serve Him. Their sudden death warned all Israel that pride, carelessness, or self-made worship in His presence brings real judgment.

What does "I will be sanctified in them that come nigh me" mean in this passage?

That line means God will show His holiness in those who come near to Him, especially in priests and leaders. If they honor His commands, His holiness is seen in mercy and fellowship. If they despise His word, His holiness is seen in judgment. He will not let His worship be treated as common or casual. Those who serve closest to Him must take Him most seriously. This verse reminds us that God chooses how He is approached, and His glory comes before our own ideas or feelings.

Why was Aaron told not to mourn outwardly for Nadab and Abihu?

Aaron and his remaining sons were told not to uncover their heads or tear their clothes, which were the usual signs of mourning, because they were on duty as priests before God. If they had mourned in that way, it would have looked like they were protesting God’s judgment instead of agreeing that He is just. The rest of Israel could weep over the burning, but the priests had to show that God’s honor comes first, even above family grief. Aaron’s silence shows a hard but real submission to God’s will.

Why did God forbid Aaron and his sons to drink wine when serving at the tabernacle?

God told Aaron that he and his sons must not drink wine or strong drink when they went into the tent of meeting. The reason was simple and serious: they had to be clear-minded to tell the difference between what is holy and what is common, and between what is clean and unclean, and to teach the people His laws. Clouded judgment would lead to more mistakes like Nadab and Abihu’s. This rule shows that those who lead in worship must be sober, careful, and able to think clearly before God.

What does this passage teach about the responsibilities of priests?

This passage shows that priests have heavy responsibilities. They must follow God’s instructions exactly in offerings, stay at their post even when life is painful, and keep themselves sober and focused in God’s presence. They are called to distinguish between holy and unholy, clean and unclean, and to teach God’s people all His statutes. When they fail, others suffer. When they obey, they help carry the people’s sin through the sacrifices God has given. Their role is both a gift and a serious trust.

Why was Moses upset that the sin offering goat was burned instead of eaten?

Moses was angry because the law said that particular sin offering, whose blood was not taken into the inner place, was to be eaten by the priests in the holy place. Eating it was part of their duty “to bear the iniquity of the congregation,” showing that they identified with the people’s sin before God. When Moses found it burned, he thought they had ignored God’s command, especially serious after Nadab and Abihu’s death for disobedience. He wanted the priests to treat every detail of God’s worship with care.

How did Aaron’s answer calm Moses about the burned sin offering?

Aaron explained that his sons had offered their sin offering and burnt offering that same day, and then this tragedy had happened to him. In his deep grief, he felt that if he had eaten the sin offering, it might not have been pleasing to God, even if the rule said he could. His point was that outward duty without a right heart would not honor God. Moses accepted this answer. This shows that God cares about both obedience and the spirit in which it is carried out.

What does this passage show about God’s holiness and human worship today?

This passage shows that God’s holiness has not changed. He cares how He is approached, and worship is not a place for our own inventions. While we are not under the old priestly system, the pattern still speaks: take God’s word seriously, do not treat holy things as common, and do not try to serve Him in a careless or self-pleasing way. It also reminds us that leaders in worship and teaching have a special duty to be sober, humble, and faithful, because their choices affect many others.

Lev.10.1

Leviticus 10:1

KJV

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.

The Sin of Nadab and Abihu

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.

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.

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.

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

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.

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.

Restrictions for Priests

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:

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.

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.

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.

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?

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.

19 And Aaron said unto Moses, Behold, this day have they offered their sin offering and their burnt offering before the Lord; and such things have befallen me: and if I had eaten the sin offering to day, should it have been accepted in the sight of the Lord?

20 And when Moses heard that, he was content.
