Jair (Hebrew יאיר Ya'ir) was a man from Gilead (Tribe of Manasseh, east of the River Jordan), who judged Israel for twenty-two years, after the death of Tola. His inheritance was in Gilead through the line of Machir, the son of Manasseh. Jair was the son of Segub, the son of Hezron the Jew through the daughter of Machir (1 Chronicles 2). According to Judges 10:3-5, Jair had thirty sons, who rode thirty ass colts, and thirty 'cities' in Gilead which came to be known as Havoth-Jair. The word chawwoth ('tent encampments') occurs only in this context (Numbers 32:41; Deuteronomy 3:14; Judges 10:4), and is a legacy word remaining from the early nomadic stage of Hebrew culture. W. Ewing suggests that Kamon probably corresponds to Kamun taken by the Seleucid king Antiochus III, on his march from Pella to Gephrun (Polybius Book V.70:12).
Jair died and was buried in Kamon.
