Isaiah 7:10-14

Then the Lord spoke again to Ahaz, saying,

“Ask for a sign for yourself from the Lord your God; make it deep as Sheol or high as heaven.”

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

Then he said, “Listen now, house of David! Is it too trivial a thing for you to try the patience of men, that you will try the patience of my God as well?

Therefore the Lord Himself will give you a sign: Behold, the virgin will conceive and give birth to a son, and she will name Him Immanuel.
