1 Chronicles 2:26

Jerahmeel had also another wife, whose name was Atarah
Distinct from his wife before named; or "another woman", which is a phrase for an harlot or concubine, ( Judges 11:2 ) which she might be, as Kimchi observes; though the former seems best:

she was the mother of Onam;
and perhaps was the only son she bore to Jerahmeel, of whose sons see ( 1 Chronicles 2:28 ) .
