TSK · Numbers 32:39

And Joseph saw Ephraim's children of the third generation: the children also of Machir the son of Manasseh were born upon Joseph's knees.

And [this] was the lot for the tribe of Manasseh; for he was the first-born of Joseph. As for Machir the first-born of Manasseh, the father of Gilead, because he was a man of war, therefore he had Gilead and Bashan.

And they vexed 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.
