Isaiah 7:11

8 For the head of Syria is Damascus, and the head of Damascus is Rezin; and within sixty-five years shall Ephraim be broken in pieces, so that it shall not be 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 Yahweh spoke again to Ahaz, saying,

11 Ask you a sign of Yahweh 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 Yahweh.

13 He said, "Listen now, house of David: Is it a small thing for you to weary men, that you will weary my God also?

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