2 Samuel 21:8

Of Michol. They were the sons of Merob, who was married to Hadriel; but they are here called the sons of Michol, because she adopted them, and brought them up as her own: (Challoner; Chaldean; St. Jerome, Trad.) or Merob ws called Michol; (Sa) or, what seems most probable, from the word she bore being used, (Cajetan) and as two sisters would hardly have the same name, (Haydock) Micholhas crept into the text instead of Merob. (Capel; Salien; Calmet) (1 Kings xxv. 44.)
