Joshua 17:1-2

1Now this was the lot (allotment) for the tribe of Manasseh, for he was the firstborn of Joseph. To Machir the firstborn of Manasseh, the father of Gilead, were allotted Gilead and Bashan, because he was a man of war.

2So the lot was also made for the rest of the sons of Manasseh according to their families—for the sons of Abiezer and for the sons of Helek and for the sons of Asriel and for the sons of Shechem and for the sons of Hepher and for the sons of Shemida; these were the male descendants of Manasseh the son of Joseph according to their families (clans).
