2 Chronicles 13:5

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.

And Abijah stood up upon mount Zemaraim, which is in mount Ephraim, and said, Hear me, thou Jeroboam, and all Israel;

Yet Jeroboam the son of Nebat, the servant of Solomon the son of David, is risen up, and hath rebelled against his lord.

And there are gathered unto him vain men, the children of Belial, and have strengthened themselves against Rehoboam the son of Solomon, when Rehoboam was young and tenderhearted, and could not withstand them.
