Isaiah 7:10-14

10Moreover the Lord spoke again to Ahaz, saying,

11“Ask a sign for yourself from the Lord your God; ask it either in the depth or in the height above.”

12But Ahaz said, “I will not ask, nor will I test the Lord!”

13Then 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?

14Therefore the Lord Himself will give you a sign: Behold, the virgin shall conceive and bear a Son, and shall call His name Immanuel.
