“When King [Aḥashverosh] was sitting [keshevet hamelekh].” Rabbi Yitzḥak said: The nations of the world do not sit securely. They objected: Is it not written: “When King [Aḥashverosh] was sitting”? He said to them: Beshevet hamelekh [while the king was sitting] is not written here, rather, keshevet hamelekh [as if the king were sitting] – sitting that is not sitting. However, the sitting of Israel is sitting, as it is stated: “When Israel sat [beshevet] in Ḥeshbon and its environs” (Judges 11:26).
