R. Elazar Hamodai says: "And Amalek came": Amalek "sneaked" under the edges of the cloud and snatched souls of Israel and killed them, viz. (Devarim 25:18) (Amalek) "who met you on the way … when you were faint and weary and (Amalek) did not fear G–d." Others say: This refers to Israel, who (at that time) did not have mitzvoth in their hands.
