Isaiah Foretells

Then Isaiah said,
"Hear now, you house of David!
Is it not enough to try the patience of men?
Will you try the patience of my God also?
Therefore the Lord Himself will give you a sign:
The virgin will be with Child
and will give birth to a Son,
and will call Him Immanuel.
He will eat curds and honey when He knows enough
to reject the wrong and choose the right.
But before the Boy knows enough
to reject the wrong and choose the right,
the land of the two kings you dread
will be laid waste.
The Lord will bring on you
and on your people
and on the house of your father
a time unlike any 
since Ephraim broke away from Judah -
He will bring the king of Assyria."

(Isaiah 7:13-17)
