Matthew Henry on 1 Kings 15:1-8
We have here a short account of the short reign of Abijam the son of Rehoboam king of Judah. He makes a better figure, 2 Chr. 13, where we have an account of his war with Jeroboam, the speech which he made before the armies engaged, and the wonderful victory he obtained by the help of God.
