Leviticus 10:1-7 - The Deaths Of Nadab And Abihu
1 Aaron's sons Nadab and Abihu each took an incense burner. They put burning coals and incense in it. Then in Jehovah's presence they offered this unauthorized fire. 2 A fire flashed from Jehovah and burned them. They died in the presence of Jehovah. 3 Moses said to Aaron: This is what Jehovah was speaking about when he said: 'All who serve me must respect my holiness. I will reveal my glory to my people.' But Aaron remained silent.
4 Moses called Mishael and Elzaphan, the sons of Uzziel, Aaron's uncle. He said: Come here and carry your cousins' bodies away from the sacred tent and put them outside the camp. 5 So they came and took hold of the clothing on the corpses. They carried them outside the camp just as Moses had commanded.
6 Moses said to Aaron and to his sons Eleazar and Ithamar: Do not leave your hair uncombed or tear your clothes to show that you are in mourning. If you do you will die. For Jehovah will be angry with the whole community. But all other Israelites are allowed to mourn this death caused by the fire Jehovah sent. 7 You are Jehovah's chosen priests. You must not leave the sacred tent, or you will die. Aaron and his two sons obeyed Moses.
