Isaiah 7:10-14

Moreover the LORD spoke again to Ahaz, saying, “Ask a sign for yourself from the LORD your God; ask it either in the depth or in the height above.” But Ahaz said, “I will not ask, nor will I test the LORD!” Then he said, “Hear now, O house of David! Is it a small thing for you to weary men, but will you weary my God also? Therefore the Lord Himself will give you a sign: Behold, the virgin shall conceive and bear a Son, and shall call His name Immanuel.
