mothers] That is, grand-mothers. All female ancestors in the right line, use to be called mothers; as male, fathers. David, his great-great grand-father (for Asa was the fourth from David) is stiled his father in the next verse. Mention useth to be made of the mothers of kings, because in their younger yeers they were most instructed by them, Proverbs 31:1. and because kings used to have many wives. Therefore by name they expressed the proper mother. It might be that Asa his own mother was dead, and he educated by his grand-mother: who though she were an idolater, yet could not infect him: which maketh much to his commendation.
