[367] So the king took this army, and marched hastily out of Antioch, with Lysias, who had the command of the whole, and came to Idumea, and thence went up to the city Bethsnra, a city that was strong, and not to be taken without great difficulty. He set about this city, and besieged it. And while the inhabitants of Bethsura courageously opposed him, and sallied out upon him, and burnt his engines of war, a great deal of time was spent in the siege. But when Judas heard of the king's coming, he raised the siege of the citadel, and met the king, and pitched his camp in certain straits, at a place called Bethzachriah, at the distance of seventy furlongs from the enemy; but the king soon drew his forces from Bethsura, and brought them to those straits. And as soon as it was day, he put his men in battle-array, and made his elephants follow one another through the narrow passes, because they could not be set sideways by one another. Now round about every elephant there were a thousand footmen, and five hundred horsemen. The elephants also had high towers [upon their backs], and archers [in them]. And he also made the rest of his army to go up the mountains, and put his friends before the rest; and gave orders for the army to shout aloud, and so he attacked the enemy. He also exposed to sight their golden and brazen shields, so that a glorious splendor was sent from them; and when they shouted the mountains echoed again. When Judas saw this, he was not terrified, but received the enemy with great courage, and slew about six hundred of the first ranks. But when his brother Eleazar, whom they called Auran, saw the tallest of all the elephants armed with royal breastplates, and supposed that the king was upon him, he attacked him with great quickness and bravery. He also slew many of those that were about the elephant, and scattered the rest, and then went under the belly of the elephant, and smote him, and slew him; so the elephant fell upon Eleazar, and by his weight crushed him to death. And thus did this man come to his end, when he had first courageously destroyed manyof his enemies.
