"Behold, a virgin shall conceive in the womb, and shall bring forth a son..."

The Prophet Isaiah prophesying of the Nativity of Christ from the Most-Holy Theotokos (source)

  
And the Lord again spoke to Achaz, saying,  Ask for thyself a sign of the Lord thy God, in the depth or in the height.  And Achaz said, I will not ask, neither will I tempt the Lord.  And he said, Hear ye now, O house of David; is it a little thing for you to contend with men? and how do ye contend against the Lord?  Therefore the Lord himself shall give you a sign; behold, a virgin shall conceive in the womb, and shall bring forth a son, and thou shalt call his name Emmanuel.  Butter and honey shall he eat, before he knows either to prefer evil or choose the good.  For before the child shall know good or evil, he refuses evil, to choose the good; and the land shall be forsaken which thou art afraid of because of the two kings.And the Lord said to me, Take to thyself a volume of a great new book, and write in it with a man's pen concerning the making a rapid plunder of spoils; for it is near at hand.  And make me witnesses of faithful men, Urias, and Zacharias the son of Barachias.  And I went in to the prophetess; and she conceived, and bore a son. And the Lord said to me, Call his name, Spoil quickly, plunder speedily.  For before the child shall know how to call his father or his mother, one shall take the power of Damascus and the spoils of Samaria before the king of the Assyrians. and he shall take away from Juda every man who shall be able to lift up his head, and every one able to accomplish anything; and his camp shall fill the breadth of thy land, O God with us. Know, ye Gentiles, and be conquered; hearken ye, even to the extremity of the earth: be conquered, after ye strengthened yourselves; for even if ye should again strengthen yourselves, ye shall again be conquered. And whatsoever counsel ye shall take, the Lord shall bring it to nought; and whatsoever word ye shall speak, it shall not stand among you: for God is with us.

"For to us a child is born, to us a son is given..."

Icon of Christ "The Angel of Great Counsel" (source)

  
For to us a child is born, to us a son is given; and the government will be upon his shoulder, and his name will be called "Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace." Of the increase of his government and of peace there will be no end, upon the throne of David, and over his kingdom, to establish it, and to uphold it with justice and with righteousness from this time forth and for evermore. The zeal of the LORD of hosts will do this.

"But the stone that struck the image became a great mountain and filled the whole earth..."

The Holy Prophet Daniel's Prophecy of the Incarnation of Christ (source)

  
"You saw, O king, and behold, a great image. This image, mighty and of exceeding brightness, stood before you, and its appearance was frightening. The head of this image was of fine gold, its breast and arms of silver, its belly and thighs of bronze, its legs of iron, its feet partly of iron and partly of clay. As you looked, a stone was cut out by no human hand, and it smote the image on its feet of iron and clay, and broke them in pieces; then the iron, the clay, the bronze, the silver, and the gold, all together were broken in pieces, and became like the chaff of the summer threshing floors; and the wind carried them away, so that not a trace of them could be found. But the stone that struck the image became a great mountain and filled the whole earth.*** "This was the dream; now we will tell the king its interpretation. And in the days of those kings the God of heaven will set up a kingdom which shall never be destroyed, nor shall its sovereignty be left to another people. It shall break in pieces all these kingdoms and bring them to an end, and it shall stand for ever; just as you saw that a stone was cut from a mountain by no human hand, and that it broke in pieces the iron, the bronze, the clay, the silver, and the gold. A great God has made known to the king what shall be hereafter. The dream is certain, and its interpretation sure."

"***This vision clearly portrayed through the mountain the height of the Virgin's holiness and the power of the Holy Spirit which overshadowed her. Through the image of the Stone, Christ was portrayed, Who was seedlessly born of her, and Who by His coming as the Godman would shatter and destroy all the kingdoms of the world, which were portrayed through the image; and He would raise them that believe in Him into His Heavenly Kingdom, which is eternal and everlasting."

"There shall come forth a shoot from the stump of Jesse..."

Icon of Christ held by the Theotokos, "The Root of Jesse" (source)

  
There shall come forth a shoot from the stump of Jesse, and a branch shall grow out of his roots. And the Spirit of the LORD shall rest upon him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and the fear of the LORD. And his delight shall be in the fear of the LORD. He shall not judge by what his eyes see, or decide by what his ears hear; but with righteousness he shall judge the poor, and decide with equity for the meek of the earth; and he shall smite the earth with the rod of his mouth, and with the breath of his lips he shall slay the wicked. Righteousness shall be the girdle of his waist, and faithfulness the girdle of his loins. The wolf shall dwell with the lamb, and the leopard shall lie down with the kid, and the calf and the lion and the fatling together, and a little child shall lead them. The cow and the bear shall feed; their young shall lie down together; and the lion shall eat straw like the ox. The sucking child shall play over the hole of the asp, and the weaned child shall put his hand on the adder's den. They shall not hurt or destroy in all my holy mountain; for the earth shall be full of the knowledge of the LORD as the waters cover the sea. In that day the root of Jesse shall stand as an ensign to the peoples; him shall the nations seek, and his dwellings shall be glorious.

"But you, O Bethlehem..."

The Grotto where Christ was born in the Basilica of the Nativity in Bethlehem (source)

 
In that day, says the LORD, I will assemble the lame and gather those who have been driven away, and those whom I have afflicted; and the lame I will make the remnant; and those who were cast off, a strong nation; and the LORD will reign over them in Mount Zion from this time forth and for evermore.  But you, O Bethlehem Eph'rathah, who are little to be among the clans of Judah, from you shall come forth for me one who is to be ruler in Israel, whose origin is from of old, from ancient days. Therefore he shall give them up until the time when she who is in travail has brought forth; then the rest of his brethren shall return to the people of Israel. And he shall stand and feed his flock in the strength of the LORD, in the majesty of the name of the LORD his God. And they shall dwell secure, for now he shall be great to the ends of the earth.

"He couched, he lay down like a lion..."

Icon of Christ and the Theotokos "O Anapeson", echoing the prophecy that mystically foreshadows the astonishing and paradoxal wonder of God sleeping in the flesh, both in gentleness as a babe, and in death through His Passion (source)

And Balaam lifted up his eyes, and saw Israel encamping tribe by tribe. And the Spirit of God came upon him, and he took up his discourse, and said, "The oracle of Balaam the son of Be'or, the oracle of the man whose eye is opened, how fair are your tents, O Jacob, your encampments, O Israel! Like valleys that stretch afar, like gardens beside a river, like aloes that the LORD has planted, like cedar trees beside the waters. Water shall flow from his buckets, and his seed shall be in many waters, his king shall be higher than Agag, and his kingdom shall be exalted. God brings him out of Egypt; he has as it were the horns of the wild ox, he shall eat up the nations his adversaries, and shall break their bones in pieces, and pierce them through with his arrows. He couched, he lay down like a lion, and like a lioness; who will rouse him up? Blessed be every one who blesses you, and cursed be every one who curses you." I see him, but not now; I behold him, but not nigh: a star shall come forth out of Jacob, and a scepter shall rise out of Israel; it shall crush the forehead of Moab, and break down all the sons of Sheth. Edom shall be dispossessed, Se'ir also, his enemies, shall be dispossessed, while Israel does valiantly.
