2 Chronicles 13:1-3

King James Version

13 Now in the eighteenth year of king Jeroboam began Abijah to reign over Judah.

² He reigned three years in Jerusalem. His mother's name also was Michaiah the daughter of Uriel of Gibeah. And there was war between Abijah and Jeroboam.

³ And Abijah set the battle in array with an army of valiant men of war, even four hundred thousand chosen men: Jeroboam also set the battle in array against him with eight hundred thousand chosen men, being mighty men of valour.
