Targum for Lamentations 1:19

Jerusalem said, when she was delivered into the hand of Nebuchadnezzar, “I called to my friends, the sons of the nations, with whom I had made treaties to come to my aid. But they deceived me and turned to destroy me. (These are the Romans who entered with Titus and the wicked Vespasian and they built siege works against Jerusalem.) My priests and my elders within the city perish from hunger, because they searched for the sustenance of bread for themselves to eat, in order to preserve their souls.
