Isaiah 7:11 to 7:14
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.
