Isaiah 7:18

18 And this shall happen: On that day, Yahweh will whistle for the fly that [is] at the end of the stream of Egypt and the bee that [is] in the land of Assyria.

Isaiah 7:18 In-Context

16 For before the boy knows to reject the evil and to choose the good, {the land whose two kings you dread will be abandoned.}
17 "Yahweh will bring on you and on your people and on the house of your ancestor days that have not come since [the] day Ephraim departed from Judah: the king of Assyria."
18 And this shall happen: On that day, Yahweh will whistle for the fly that [is] at the end of the stream of Egypt and the bee that [is] in the land of Assyria.
19 And all of them will come and settle in the rivers of the cliffs and in the clefts of the rocks and on all of the thornbushes and watering places.
20 On that day, the Lord will shave the head and the hair of the feet with a razor of the one hired from beyond [the] river--with the king of Assyria--and it will even take off the beard.
