Isaiah 7:8-14

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

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

10 Moreover the LORD spoke again to Ahaz, saying,

11 Ask you a sign of the LORD your God; ask it either in the depth, or in the height above.

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

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

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