Albert Barnes Commentary Numbers 32:41

"And Jair the son of Manasseh went and took the towns thereof, and called them Havvoth-jair." — Numbers 32:41 (ASV)

The exploits of Jair—he was the conqueror of Argob (Deuteronomy 3:14)—gave new luster to his name; and the fame of the family is attested by the history of Jair the Israelite judge, doubtless a descendant; perhaps also by the mention of Jairus (Luke 8:41), the ruler of the synagogue at the neighboring city of Capernaum.

Havoth-jair— That is, the villages, or rather groups of tents, or “kraals,” of Jair.
