[287] WHEN Apollonius, the general of the Samaritan forces, heard this, he took his army, and made haste to go against Judas, who met him, and joined battle with him, and beat him, and slew many of his men, and among them Apollonius himself, their general, whose sword being that which he happened then to wear, he seized upon, and kept for himself; but he wounded more than he slew, and took a great deal of prey from the enemy's camp, and went his way. But when Seron, who was general of the army of Celesyria, heard that many had joined themselves to Judas, and that he had about him an army sufficient for fighting, and for making war, he determined to make an expedition against him, as thinking it became him to endeavor to punish those that transgressed the king's injunctions. He then got together an army, as large as he was able, and joined to it the runagate and wicked Jews, and came against Judas. He came as far as Bethhoron, a village of Judea, and there pitched his camp; upon which Judas met him; and when he intended to give him battle, he saw that his soldiers were backward to fight, because their number was small, and because they wanted food, for they were fasting, he encouraged them, and said to them, that victory and conquest of enemies are not derived from the multitude in armies, but in the exercise of piety towards God; and that they had the plainest instances in their forefathers, who, by their righteousness, exerting themselves on behalf of their own laws, and their own children, had frequently conquered many ten thousands, - for innocence is the strongest army. By this speech he induced his men to contenm the multitude of the enemy, and to fall upon Seron. And upon joining battle with him, he beat the Syrians; and when their general fell among the rest, they all ran away with speed, as thinking that to be their best way of escaping. So he pursued them unto the plain, and slew about eight hundred of the enemy; but the rest escaped to the region which lay near to the sea.
