Isaiah 7:12 (KJV)

Thus saith the Lord GOD, It shall not stand, neither shall it come to pass.

For the head of Syria is Damascus, and the head of Damascus is Rezin; and within threescore and five years shall Ephraim be broken, that it be not a people.

And the head of Ephraim is Samaria, and the head of Samaria is Remaliah's son. If ye will not believe, surely ye shall not be established.

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.

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.

Butter and honey shall he eat, that he may know to refuse the evil, and choose the good.

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.
