Balaam said: Of the seventy nations that the Holy One, blessed be He, created in His world, He did not put His name on any one of them except on Israel; and since the Holy One, blessed be He, made the name of Ishmael similar to the name of Israel, woe to him who shall live in his days, as it is said, "Alas, who shall live when God establisheth him?" (Num. 24:23).
Rabbi Ishmael said: In the future the children of Ishmael will do fifteen things in the land (of Israel) in the latter days, and they are: They will measure the land with ropes; they will change a cemetery into a resting-place for sheep (and) a dunghill; they will measure with them and from them upon the tops of the mountains; falsehood will multiply and truth will be hidden; the statutes will be removed far from Israel; sins will be multiplied in Israel; worm-crimson will be in the wool, and he will cover with insects paper and pen; he will hew down the rock of the kingdom, and they will rebuild the desolated cities and sweep the ways; and they will plant gardens and parks, and fence in the broken walls of the Temple; and they will build a building in the Holy Place; and two brothers will arise over them, princes at the end; and in their days the Branch, the Son of David, will arise, as it is said, || "And in the days of those kings shall the God of heaven set up a kingdom, which shall never be destroyed" (Dan. 2:44).
