Таргум к Бамидбар 24:20

And he looked on the house of Amalek, and took up the parable of his prophecy, and said: The first of the nations who made war with the house of Israel were those of the house of Amalek; and they at last, in the days of the King Meshiha, with all the children of the east, will make war against Israel; but all of them together will have eternal destruction in their end.

And he beheld the Amalkaah, and took up the parable of his prophecy and said: The house of Amalek was the first of the peoples to make war with Israel, and at last in the end of the days they will array battle against them; but their end is to perish, and their destruction to be for ever.
