[274] Yet did not Jeroboam lay any of these things to heart, but he brought together a very numerous army, and made a warlike expedition against Abijah, the son of Rehoboam, who had succeeded his father in the kingdom of the two tribes; for he despised him because of his age. But when he heard of the expedition of Jeroboam, he was not affrighted at it, but proved of a courageous temper of mind, superior both to his youth and to the hopes of his enemy; so he chose him an army out of the two tribes, and met Jeroboam at a place called Mount Zemaraim, and pitched his camp near the other, and prepared everything necessary for the fight. His army consisted of four hundred thousand, but the army of Jeroboam was double to it. Now as the armies stood in array, ready for action and dangers, and were just going to fight, Abijah stood upon an elevated place, and beckoning with his hand, he desired the multitude and Jeroboam himself to hear first with silence what he had to say. And when silence was made, he began to speak, and told them, - "God had consented that David and his posterity should be their rulers for all time to come, and this you yourselves are not unacquainted with; but I cannot but wonder how you should forsake my father, and join yourselves to his servant Jeroboam, and are now here with him to fight against those who, by God's own determination, are to reign, and to deprive them of that dominion which they have still retained; for as to the greater part of it, Jeroboam is unjustly in possession of it. However, I do not suppose he will enjoy it any longer; but when he hath suffered that punishment which God thinks due to him for what is past, he will leave off the transgressions he hath been guilty of, and the injuries he hath offered to him, and which he hath still continued to offer and hath persuaded you to do the same: yet when you were not any further unjustly treated by my father, than that he did not speak to you so as to please you, and this only in compliance with the advice of wicked men, you in anger forsook him, as you pretended, but, in reality, you withdrew yourselves from God, and from his laws, although it had been right for you to have forgiven a man that was young in age, and not used to govern people, not only some disagreeable words, but if his youth and unskilfulness in affairs had led him into some unfortunate actions, and that for the sake of his father Solomon, and the benefits you received from him; for men ought to excuse the sins of posterity on account of the benefactions of parent; but you considered nothing of all this then, neither do you consider it now, but come with so great an army against us. And what is it you depend upon for victory? Is it upon these golden heifers, and the altars that you have on high places, which are demonstrations of your impiety, and not of religious worship? Or is it the exceeding multitude of your army which gives you such good hopes? Yet certainly there is no strength at all in an army of many ten thousands, when the war is unjust; for we ought to place our surest hopes of success against our enemies in righteousness alone, and in piety towards God; which hope we justly have, since we have kept the laws from the beginning, and have worshipped our own God, who was not made by hands out of corruptible matter; nor was he formed by a wicked king, in order to deceive the multitude; but who is his own workmanship, ¹ and the beginning and end of all things. I therefore give you counsel even now to repent, and to take better advice, and to leave off the prosecution of the war; to call to mind the laws of your country, and to reflect what it hath been that hath advanced you to so happy a state as you are now in."
