[203] But Trypho removed from Ptoeinais with a great army, and came into Judea, and brought Jonathan with him in bonds. Simon also met him with his army at the city Adida, which is upon a hill, and beneath it lie the plains of Judea. And when Trypho knew that Simon was by the Jews made their governor, he sent to him, and would have imposed upon him by deceit and trencher, and desired, if he would have his brother Jonathan released, that he would send him a hundred talents of silver, and two of Jonathan's sons as hostages, that when he shall be released, he may not make Judea revolt from the king; for that at present he was kept in bonds on account of the money he had borrowed of the king, and now owed it to him. But Simon was aware of the craft of Trypho; and although he knew that if he gave him the money he should lose it, and that Trypho would not set his brother free and withal should deliver the sons of Jonathan to the enemy, yet because he was afraid that he should have a calumny raised against him among the multitude as the cause of his brother's death, if he neither gave the money, nor sent Jonathan's sons, he gathered his army together, and told them what offers Trypho had made; and added this, that the offers were ensnaring and treacherous, and yet that it was more eligible to send the money and Jonathan's sons, than to be liable to the imputation of not complying with Trypho's offers, and thereby refusing to save his brother. Accordingly, Simon sent the sons of Jonathan and the money; but when Trypho had received them, he did not keep his promise, nor set Jonathan free, but took his army, and went about all the country, and resolved to go afterward to Jerusalem by the way of Idumea, while Simon went over against him with his army, and all along pitched his own camp over against his.
