Joshua 13:29-31

Ver. 29-31. And Moses gave inheritance unto the half tribe of Manasseh— It does not appear that the tribe of Manasseh had desired the settlements which Moses gave to the half tribe of it on the east of Jordan, Numbers 32:1-2. But as it was numerous, Num 26:34 and had evidently much cattle, Moses thought proper to associate the half with the tribes of Reuben and Gad. The country was extensive. The half tribe of Manasseh, placed on the north, covered the two others; and Moses, by placing it there, rewarded the family of Machir, who was so famous for his valour in the war against Og. Numbers 32:39.
