Charles Ellicott Commentary 1 Chronicles 7:14

"The sons of Manasseh: Asriel, whom his concubine the Aramitess bare: she bare Machir the father of Gilead:" — 1 Chronicles 7:14 (ASV)

The sons of Manasseh. —Translate, the sons of Manasseh, Asriel, whom his Aramean concubine bore. (She bore Machir, father of Gilead.)Numbers 27:1, Joshua 17:3, give the line

Zelophehad has five daughters, but no sons. Numbers 26:29–33 gives the same line with additions thus:—

This last passage is important, because it expressly declares that the names all represent clans, with the exception of Zelophehad, who had no sons, but daughters. It also shows that Asriel was great-grandson of Manasseh. The parenthesis of 1 Chronicles 7:14, therefore, appears to be intended to warn the reader that Asriel was the “son” of the Aramean concubine of Manasseh, mediately through descent from Machir.
