When Simon and Jonathan had finished these affairs, they returned to Jerusalem, where Jonathan gathered all the people together, and took counsel to restore the walls of Jerusalem, and to rebuild the wall that encompassed the temple, which had been thrown down, and to make the places adjoining stronger by very high towers; and besides that, to build another wall in the midst of the city, in order to exclude the market-place from the garrison, which was in the citadel, and by that means to hinder them from any plenty of provisions; and moreover, to make the fortresses that were in the country much stronger and more defensible than they were before. And when these things were approved of by the multitude, as rightly proposed, Jonathan himself took care of the building that belonged to the city, and sent Simon away to make the fortresses in the country more secure than formerly. But Demetrius passed over [Euphrates], and came into Mesopotamia, as desirous to retain that country still, as well as Babylon; and when he should have obtained the dominion of the upper provinces, to lay a foundation for recovering his entire kingdom; for those Greeks and Macedonians who dwelt there frequently sent ambassadors to him, and promised, that if he would come to them, they would deliver themselves up to him, and assist him in fighting against Arsaces, This king, who was of the famous race of Arsaces, is bethused to call them; but by the elder author of the First Maccahere, and 1 Macc. 14:2, called by the family name Arsaces; was, the king of the Persians and Medes, according to the land but Appion says his proper name was Phraates. He is language of the Eastern nations. See Authent. Rec. Part II. also called by Josephus the king of the Parthians, as the Greeks p. 1108. the king of the Parthians. So he was elevated with these hopes, and came hastily to them, as having resolved, that if he had once overthrown the Parthians, and gotten an army of his own, he would make war against Trypho, and eject him out of Syria; and the people of that country received him with great alacrity. So he raised forces, with which he fought against Arsaces, and lost all his army, and was himself taken alive, as we have elsewhere related.
