“But do this for them, and they will live, and will not die upon their approaching the Holy of Holies. Aaron and his sons shall come and assign them, each man to his service and to his burden” (Numbers 4:19). “But do this [vezot] for them, and they will live, and will not die….” “But do this for them,” just as it wrote “this [zot]” regarding Aaron, “with this [bezot] Aaron shall come…” (Leviticus 16:3), here, too, zot is written.
Just as He instituted a remedy for Aaron, so He did for them: “And they will live and will not die.” The Holy One blessed be He said to them: ‘Institute a remedy for the sons of Kehat so that they will live and will not die upon their approaching the Ark, as were it not for them, Israel would not survive.’ Why? It is because these four families, Gershon, Kehat, Merari, and Aaron and his sons, surround the Tent of Meeting.
If Israel were sullied with a matter, and punishment came to emerge from the Tent of Metting due to the Divine Presence, immediately, the sons of Kehat, who were encamped near the Tent of Meeting, would stand and curb it, so it would not emerge against them. From where is it derived? From the verse: “The Levites shall encamp around the [Tabernacle of the testimony, and there shall not be rage against the congregation of the children of Israel]” (Numbers 1:53).
Rabbi Pinḥas HaKohen bar Ḥama said: If you do not derive it from here, you have from elsewhere to derive it. When Koraḥ came to dispute Moses, the angel of death came to emerge against Israel and to damage them. Had it emerged, it would have killed all of Israel. Moses was encamped near the Tent of Meeting, as he was a member of the sons of Kehat.
He sensed that it sought to emerge against Israel. Immediately, he said to Aaron: ‘“Take the fire pan, and place fire upon it from on the altar…and atone for them” (Numbers 17:11). Quickly, with alacrity, hurry, why are you standing and dallying? “Go quickly to the congregation”’ (Numbers 17:11).
Aaron said to him: ‘What have you seen?’ He said to him: ‘I saw the angel of death who emerged to afflict the enemies of Israel:12A euphemism for Israel. “For the rage has emerged from before the Lord”’ (Numbers 17:11). You learn that the Levites would curb the punishments, among them the sons of Kehat, who were the bearers of the Ark.
The Holy One blessed be He said to them: ‘They suffer with Israel all this suffering, and you do not institute a remedy for them?’
