Leviticus 10:1-3

Leeser(i) 1 And Nadab and Abihu, the sons of Aaron, took each his censer, and they put therein fire, and put thereon incense: and they brought near before the Lord a strange fire, which he had not commanded them. 2 And there went out a fire from before the Lord, and consumed them, and they died before the Lord. 3 Then said Moses unto Aaron, This is what the Lord hath spoken, saying, On those who are near unto me will I be sanctified, and before all the people will I be glorified: and Aaron held his peace.
