Isaiah 7:12-14

"But Ahaz said, 'I will not ask, nor will I test the Lord!'"

"Then he said, 'Hear now, oh 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.'"
