On, son of Pelet, was a Reubenite who joined Korah's rebellion against the leadership of Moses and Aaron in the wilderness. He is mentioned only briefly in Numbers 16:1, and his further fate is not explicitly described in the text. Some Jewish traditions claim that his wife persuaded him to withdraw from the rebellion.

2They rose up against Moses, together with two hundred and fifty men of Israel, leaders of the community, appointed members of the assembly, men of reputation.
3They gathered against Moses and Aaron and said to them, "You have gone too far! The whole community is holy, every one of them, and the LORD is among them. Why then do you set yourselves above the LORD's assembly?"
God punished the rebels by opening the earth and swallowing Korah, Dathan, and Abiram along with their families and possessions. On is not explicitly mentioned in the description of the punishment.
The rebellion against Moses and Aaron became a lasting warning to the people of Israel about the consequences of rebelling against God's chosen leaders.
9and the sons of Eliab were Nemuel, Dathan, and Abiram. It was this Dathan and Abiram, chosen leaders of the community, who contended against Moses and Aaron in the company of Korah, when they contended against the LORD.
10The earth opened its mouth and swallowed them along with Korah, when that company died and the fire consumed 250 men, and they became a warning sign.
