Numbers 26:11

Notwithstanding, the children of Korah died not.
] Neither of the pestilence, nor by fire, nor by the swallowing up of the earth; they not being in the counsel of their father, but followed the doctrine of Moses the prophet, as the Targum of Jonathan; they either disliked their father's scheme, or, if they engaged with him in it, they repented and departed from him, and were not present when the judgments of God came upon him and his company; there were several of his posterity who were singers in the times of David, and to whom many of the psalms were sent to be sung.
