Ephrem the Syrian : "Now in the eighteenth year of King Jeroboam son of Nebat, Abijam began to reign over Judah," and under his rule the Jews obtained a magnificent victory over the Israelites in a battle, which was greater than all those fought before in their civil wars. It is said that after the two multitudes of soldiers were drawn up in fighting order, Abijam appeared to have four hundred thousand men, and Jeroboam eight hundred thousand. The Jews won, while the number of the Israelites who fell in action was larger than five hundred thousand, which is an extremely rare occurrence in history. — ON THE FIRST BOOK OF KINGS 15:1
