1 Kings 15:1,2

Reigned Abijam over Judah So his reign began with Jeroboam's eighteenth year, continued his whole nineteenth year, and ended within his twentieth year, in which also Asa's reign began; and thus one and the same year may be attributed to two several persons. Three years reigned he, &c. That is, part of three years. The daughter of Abishalom Or, of Absalom, as he is called 2 Chronicles 11:21; and because he is here mentioned as a known person, without any addition of his kindred or quality, some conceive that this was Absalom's daughter, called properly Tamar, (2 Samuel 14:27,) and from her royal grandmother, (2 Samuel 3:3,) Maacah.
