Maachah (mâ'a-kah). 1. The daughter of Nahor, Abraham's brother. Genesis 22:24. 2. The father of Achish, who was king of Gath in Solomon's reign, 1 Kings 2:39; is also called Moach. 1 Samuel 27:2. 3. The daughter or more probably the granddaughter of Absalom, and the third wife of Rehoboam, mother to Abijah and grandmother to Asa, 1 Kings 15:2; 2 Chronicles 11:20-22; but the R. V. reads "Maacah." In 2 Chronicles 13:2 she is called "Michaiah, the daughter of Uriel of Gibeah," "Michaiah" being a variation of "Maachah," and Uriel being the husband of Absalom's daughter Tamar. In the beginning of Asa's reign she held the dignity of queen-mother, 1 Kings 15:2; 1 Kings 15:10; 1 Kings 15:13; 2 Chronicles 11:20-22; but when Asa came of age she lost the dignity as a punishment because she had introduced idolatry. 2 Chronicles 15:16.
