Midrasz do Estery 8:13

“The text of the document was that an edict be issued in every province, to be publicly displayed to all the peoples: Be ready for that day” (Esther 3:14).
“The text of the document” – an exact copy of the document. That an edict be issued in every province, to be publicly displayed to all the peoples: Be ready for that day.” Rabbi Levi said: The prophecy of the nations of the world is obscure, and they do not know whether it [the edict] is to be killed or to kill. This is analogous to a person who was walking along the way, and from the rigor of the way he sprained his ankle. He said: ‘If only I had a donkey.’ A Roman whose donkey had just given birth to a foal passed by him and said to him: ‘Take this foal and carry it on your shoulders.’ He said: ‘My prayer was answered, but I didn’t ask appropriately, whether it was to ride or to be ridden by.’ So is the prophecy of the nations of the world: “Be ready for that day,” but they do not know whether it is [for them] to kill or to be killed. For Israel, however, their prophecy is explicit: “For the Jews to be ready for that day, to take vengeance against their enemies” (Esther 8:13).
