Isaiah 7:20

20 When that day comes, Adonai will shave - with a razor hired beyond the [Euphrates] River, that is, with the king of Ashur - the head and the hair between the legs, and get rid of the beard as well.

Isaiah 7:20 In-Context

18 Yes, when that day comes, ADONAI will whistle for the fly in the farthest streams of the Nile in Egypt and for the bee in the land of Ashur.
19 They will come and settle, all of them, in steep vadis and holes in the rocks and on all thorn bushes and brambles.
20 When that day comes, Adonai will shave - with a razor hired beyond the [Euphrates] River, that is, with the king of Ashur - the head and the hair between the legs, and get rid of the beard as well.
21 When that day comes, a man will raise a young cow and two sheep.
22 Will they produce in abundance? No, he will [have to] eat curdled milk. Indeed, everyone left in the land will eat curdled milk and [wild] honey.
