Isaiah 7:11-15

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.

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