Isaiah 7:10-16; 8.1-4; 8:8-10 (Eve of the Nativity)
Again the LORD spoke to Ahaz, "Ask a sign of the LORD your God; let it be deep as Sheol or high as heaven." But Ahaz said, "I will not ask, and I will not put the LORD to the test." And he said, "Hear then, O house of David! Is it too little for you to weary men, that you weary my God also? Therefore the Lord himself will give you a sign. Behold, a young woman shall conceive and bear a son, and shall call his name Imman'u-el. He shall eat curds and honey when he knows how to refuse the evil and choose the good. For before the child knows how to refuse the evil and choose the good, the land before whose two kings you are in dread will be deserted.
And it will sweep on into Judah, it will overflow and pass on, reaching even to the neck; and its outspread wings will fill the breadth of your land, O Imman'u-el." Be broken, you peoples, and be dismayed; give ear, all you far countries; gird yourselves and be dismayed; gird yourselves and be dismayed. Take counsel together, but it will come to nought; speak a word, but it will not stand, for God is with us.
