2 Chronicles 13:3

Abijah went into battle with an army of 400,000 chosen men, while Jeroboam drew up in formation against him with 800,000 chosen and mighty men of valor.

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.
