Isaiah 7:10-14

10Moreover the LORD spoke again to Ahaz, saying,1 11Ask thee a sign from the LORD thy God; ask it either in the depth, or in the height above.2 12But Ahaz said, I will not ask, neither will I tempt the LORD. 13And 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? 14Therefore the Lord himself shall give you a sign; Behold, the virgin shall conceive, and bear a son, and shall call his name Immanuel.3
