Numbers 32:41

And Jair the son of Manasseh
By his mother's side, otherwise he was of the family of Judah; for Hezron, of the family of Judah, married a daughter of Machir, the son of Manasseh, by whom he had a son called Segub, who was the father of Jair, ( 1 Chronicles 2:21 1 Chronicles 2:22 ) , the same

went and took the small towns thereof;
of that part of Gilead given to Machir:

and called them Havothjair;
after his own name: in ( Deuteronomy 3:14 ) , they are called Bashanhavothjair.
