Numbers 32:39-41

And the children of Machir the son of Manasseh went to Gilead, and took it, and dispossessed the Amorite which was in it. And Moses gave Gilead unto Machir the son of Manasseh; and he dwelt therein. And Jair the son of Manasseh went and took the small towns thereof, and called them Havoth-jair.
