Isaiah 7:13-14

7:13 So Isaiah replied, “Pay attention, family of David. Do you consider it too insignificant to try the patience of men? Is that why you are also trying the patience of my God? 7:14 For this reason the sovereign master himself will give you a confirming sign. Look, this young woman is about to conceive and will give birth to a son. You, young woman, will name him Immanuel.
