亞倫的兒子拿答、亞比戶各拿自己的香爐，盛上火，加上香，在耶和華面前獻上凡火，是耶和華沒有吩咐他們的， 就有火從耶和華面前出來，把他們燒滅，他們就死在耶和華面前。 利未記 10:1-2
Nadab and Abihu were sons of Aaron. They put hot material in the pots that they used to burn incense. They threw incense over the hot material. They offered the incense to the Lord. This was a wrong thing to do. The Lord had not told them that they should do it. So it was wrong. The Lord was angry and he sent fire to burn them. They died there in front of the Lord’s altar. Leviticus 10:1-2
