Isaiah 7:10-15

And Jehovah spake again unto Ahaz, saying, Ask thee a sign of Jehovah thy God; ask it either in the depth, or in the height above. But Ahaz said, I will not ask, neither will I tempt Jehovah. And he said, Hear ye now, O house of David: Is it a small thing for you to weary men, that ye will weary my God also? Therefore the Lord himself will 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, when he knoweth to refuse the evil, and choose the good.
