C. F. Keil and Franz Delitzsch on Leviticus 10:4-5

Lev 10:4-5

Moses then commanded Mishael and Elzaphan, the sons of Uzziel Aaron’s paternal uncle, Aaron’s cousins therefore, to carry their brethren (relations) who had been slain from before the sanctuary out of the camp, and, as must naturally be supplied, to bury them there. The expression, “before the sanctuary” (equivalent to “before the tabernacle of the congregation” in Lev 9:5), shows that they had been slain in front of the entrance to the holy place. They were carried out in their priests’ body-coats, since they had also been defiled by the judgment. It follows from this, too, that the fire of Jehovah had not burned them up, but had simply killed them as with a flash of lightning.
