Numbers 16 begins (ESV):
Now Korah the son of Izhar, son of Kohath, son of Levi, and Dathan and Abiram the sons of Eliab, and On the son of Peleth, sons of Reuben, took men
They rebelled and lost. The Lord punished them:
23 And the Lord spoke to Moses, saying, 24 “Say to the congregation, Get away from the dwelling of Korah, Dathan, and Abiram.” 25 Then Moses rose and went to Dathan and Abiram, and the elders of Israel followed him. 26 And he spoke to the congregation, saying, “Depart, please, from the tents of these wicked men, and touch nothing of theirs, lest you be swept away with all their sins.”
Korah, Dathan, Abiram, their families, and 250 people total died.
On the son of Peleth isn't mentioned by name after the first verse. What happened to him? Was he one of the 250 (but not named, unlike other two) or did he stop being part of the rebellion or something else?
