|The sons of Aharon, Nadav and Avihu...brought
before Hashem a strange fire that He had not commanded them. A
fire came forth from before Hashem and consumed them; and they
died before Hashem. Moses said to Aharon: of this did Hashem speak,
saying: 'I will be sanctified through those who are nearest Me,
thus I will be honored before the entire people...'
--Parashat Shemini, Lev. 10:1-3
