Isaiah 7:15 (KJV)

Moreover the LORD spake again unto Ahaz, saying,

Ask thee a sign of the LORD thy God; ask it either in the depth, or in the height above.

But Ahaz said, I will not ask, neither will I tempt the LORD.

And he said, Hear ye now, O house of David; Is it a small thing for you to weary men, but will ye weary my God also?

Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.

For before the child shall know to refuse the evil, and choose the good, the land that thou abhorrest shall be forsaken of both her kings.

The LORD shall bring upon thee, and upon thy people, and upon thy father's house, days that have not come, from the day that Ephraim departed from Judah; even the king of Assyria.

And it shall come to pass in that day, that the LORD shall hiss for the fly that is in the uttermost part of the rivers of Egypt, and for the bee that is in the land of Assyria.

And they shall come, and shall rest all of them in the desolate valleys, and in the holes of the rocks, and upon all thorns, and upon all bushes.

In the same day shall the Lord shave with a razor that is hired, namely, by them beyond the river, by the king of Assyria, the head, and the hair of the feet: and it shall also consume the beard.
