Isaiah 7:12-14

But Ahaz said, “I will not ask, nor will I test the LORD!” Then Isaiah said, “Hear then, O house of David! Is it too small a thing for you to try the patience of men, but will you try the patience of my God as well? Therefore the Lord Himself will give you a sign: Listen carefully, the virgin will conceive and give birth to a son, and she will call his name Immanuel (God with us). [Is 9:6; Jer 31:22; Mic 5:3-5; Matt 1:22, 23]
