1 Kings 15:2

Three years reigned he in Jerusalem. And his mother's name was Maachah, the daughter of Abishalom.

Three years reigned he - (cf. 1 Kings 15:1 with 1 Kings 15:9.) Parts of years are counted in Scripture as whole years. The reign began in Jeroboam's 18th year, continued until the 19th year, and ended in the course of the 20th year.

His mother's name was Maachah - or Michaiah (2 Chronicles 13:2), probably altered from the one to the other on her becoming queen, as was very common under a change of circumstances. She is called the daughter of Abishalom, or Absalom (2 Chronicles 11:21), or Uriel (2 Chronicles 13:2). Hence, it has been thought probable that Tamar, the daughter of Absalom (2 Samuel 14:27; 2 Samuel 18:18), had been married to Uriel, and that Maachah was their daughter.
