1 Kings 15:10

And his mother's namewas Maachah, the daughter of Abishalom The most probable explanation of this clause, which is the same as in 1 Kings 15:2 above, is that the word -mother" is here used for -grandmother," and that Asa's own mother sank into small importance in comparison with her mother-in-law. Clearly Maachah was a leader of the idol worship in the land, which made it necessary for Asa to deprive her of her influence. On the power wielded in the East by a queen-mother, see 1 Kings 2:19 note. The LXX. (Vat.) gives -Ana" as the name of Asa's mother, and not -Maachah," but this is not supported by any other evidence.
