Scriptural Witness
Jair appears within the catalogue of judges in Judges 10, where his notice immediately follows that of Tola of Issachar and precedes the account of Jephthah. The text places him in Gilead, the territory east of the Jordan, and a genealogical tradition preserved at 1 Chronicles 2:21-23 connects the family and towns of Jair to the line of Manasseh through Machir; that parallel passage reckons the associated settlements as twenty-three rather than thirty.
Beyond the duration of his rule, his burial place, and the notice of his thirty sons and their towns, Scripture records no specific deeds, battles, or sayings. The Orthodox tradition honors him not through an individual hagiography but as one of the righteous forefathers of Israel, commemorated collectively on the Sunday of the Holy Forefathers before the feast of the Nativity.
