God punished Israel, who had shown themselves an ungrateful people, by sending against them an enemy that was ungrateful, too, never recalling that he owed his life to the sons of Jacob, who had had him in their power after their brilliant victory over Esau and his followers.
In his expedition against Israel he made use of his kinsman. Before going over to open attack, he lured many unsuspecting Jews to death by his kindly words. He had fetched from Egypt the table of descent of the Jews; for every Jew had there to mark his name on the bricks produced by him, and these lists lay in the Egyptian archives. Familiar with the names of the different Jewish families, Amalek appeared before the Jewish camp, and calling the people by name, he invited them to leave the camp, and come out to him. "Reuben! Simeon! Levi! etc.," he would call, "come out to me, your brother, and transact business with me."
