TSK · Numbers 32:39

Joseph saw Ephraim's children to the third generation. The children also of Machir, the son of Manasseh, were born on Joseph's knees.

This was the lot for the tribe of Manasseh, for he was the firstborn of Joseph. As for Machir the firstborn of Manasseh, the father of Gilead, because he was a man of war, therefore he had Gilead and Bashan.

They troubled and oppressed the children of Israel that year: eighteen years [oppressed they] all the children of Israel that were beyond the Jordan in the land of the Amorites, which is in Gilead.
