2 Chronicles 13:1

1In the eighteenth year of King Jeroboam, Abijah began to reign over Judah.

2He reigned three years in Jerusalem. His mother’s name was Micaiah the daughter of Uriel of Gibeah. There was war between Abijah and Jeroboam.

3Abijah joined battle with an army of valiant men of war, even four hundred thousand chosen men; and Jeroboam set the battle in array against him with eight hundred thousand chosen men, who were mighty men of valor.
