Numbers 32:39

The children of Machir -Machir, the son of Manasseh, was long since dead: even his sons had been brought up upon Joseph’s kneesGenesis 50:23. But the renown acquired by his descendants raised his family almost to the dignity of a tribe; and the Machirites are in the next verse styled Machir, just as the children of Judah or of Ephraim are often spoken of as Judah or Ephraim. So inJudges 5:14Machir is coupled with Ephraim and Zebulun. Went -i. e., “had gone:” the statement is preparatory to the ensuing record of the grant to them of the land they had won. Gilead -More strictly part of north Gilead; which, though inhabited by the Amorites, had belonged to the kingdom of Og.
