'Queen mother' in the Bible

And also as to Maachah the mother of Asa the king, he removed her from being queen mother, because she had made an idol in a grove. And Asa cut down her idol and stamped it and burned it at the torrent Kidron.

Say to the king and to the queen mother, Humble yourselves, sit down; for your greatness shall come down, even the crown of your glory.

(After Jeconiah the king, and the queen mother, and the eunuchs, the rulers of Judah and Jerusalem, and the craftsmen, and the smiths, had departed from Jerusalem.)
