"When was such a wonder of wonders ever seen by men?"

The Most-holy Theotokos and Christ (Source)

  
When was such a wonder of wonders ever seen by men? How does the Queen of all lie breathless? How has the Mother of Jesus reposed? Thou, O Virgin, wast the preaching of the prophets; thou art heralded by us. All the people venerate thee; the angels glorify thee. Rejoice, thou who art full of grace, the Lord is with thee, and through thee, with us. With Gabriel we hymn thee, with the angels we glorify thee; and with the prophets we praise thee, for they announced thee.
  
Habakkum beheld thee as an overshadowed mountain, for thou art covered with the gifts of the Holy Spirit. Daniel beheld thee as a mountain from whom, seedlessly, the solid and strong King, the Christ, issued forth. Jacob saw thee as a ladder upon Whom Christ came down to eat and drink with us. And although we, His slaves, contemplate ascending into the heavens, yet thou hast ascended before all. Rejoice, O Virgin, for Gideon beheld thee as a fleece. David saw thee as the virgin daughter of the King. Isaias called thee Mother of God and Ezekiel a gate. All the prophets prophesied thee!
  
What shall we call thee, O Virgin? Paradise. It is meet, for thou hast blossomed forth the flower of incorruption, Christ, Who is the sweet-smelling fragrance for the souls of men. Virgin? Verily, a virgin thou art, for without the seed of man thou gavest birth to our Lord Jesus Christ. Thou wast a virgin before birth and virgin at birth and still a virgin after. Shall we call thee Mother? This is meet too; for as a Mother thou gavest birth to Christ the King of all. Shall we name thee Heaven? This thou art also for upon thee rose the Sun of righteousness. Wherefore, rejoice O Virgin, and hasten to thy Son’s rest and dwell in the tents of His beloved. Hasten there and make ready a palace and remember us and all thy people also, too. O Lady Mother of God, for both we and thyself are of the race of Adam. On account of this, intercede on our behalf; for this supplicate thy Son Whom thou hast held in thine embrace, and help us in our preaching and then afterwards that we may find rest in our hopes. Go forward, O Virgin from earth to heaven, from corruption to incorruption, from the sorrow of this world to the joy of the Kingdom of the heavens, from this perishable earth to the everlasting Heaven. Hasten, O Virgin to the heavenly light, to the hymns of the angels, to the glory of the saints from all the ages. Hasten, O Virgin, to the place of thy Son, to His Kingdom, to His power, where the angels chant, the prophets glorify and the Archangels hymn the Mother of the King, who is the lit lampstand, wider than the heavens, the firmament above, the protection of Christians, and the mediatress of our race.”

Most-holy Theotokos save us!

"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.

"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.

"Let my soul rejoice in the Lord; for He hath clothed me in the garment of salvation..."

Christ is risen! Truly He is risen!

Christ beholding the risen Christ (source)

  

Let my soul rejoice in the Lord; for He hath clothed me in the garment of salvation, and with the vesture of gladness hath He covered me: he hath placed a crown upon me as on a bridegroom, and He hath adorned me as a bride with comeliness. And as the earth putting forth her flowers, and as a garden its seed; so shall the Lord, even the Lord, cause righteousness to spring forth, and exultation before all nations. For Zion's sake I will not hold my peace, and for Jerusalem's sake I will not rest, until her righteousness go forth as light, and my salvation burn as a torch. And the Gentiles shall see thy righteousness, and kings thy glory: and one shall call thee by a new name, which the Lord shall name. And thou shalt be a crown of beauty in the hand of the Lord, and a royal diadem in the hand of thy God. And thou shalt no more be called Forsaken; and thy land shall no more be called Desert: for thou shalt be called My Pleasure, and thy land Inhabited: for the Lord has taken pleasure in thee, and thy land shall be inhabited. And as a young man lives with a virgin, so shall thy sons dwell in thee: and it shall come to pass that as a bridegroom will rejoice over a bride, so will the Lord rejoice over thee.

"Shine, Shine, O Jerusalem, for thy light is come, and the glory of the Lord is risen upon thee..."

Christ is risen! Truly He is risen!

The Holy Myrrhbearers beholding the empty Tomb of Christ at His Resurrection (source)

    

"Shine, Shine, O Jerusalem, for thy light is come, and the glory of the Lord is
risen upon thee. Behold, darkness shall cover the earth, and there shall be gross

darkness on the nations: but the Lord shall appear upon thee, and his glory shall be

seen upon thee. And kings shall walk in thy light, and nations in thy brightness. Lift
up thine eyes round about, and behold thy children gathered: all thy sons have come

from far, and thy daughters shall be borne on men's shoulders. Then shalt thou see,

and fear, and be amazed in thine heart; for the wealth of the sea shall come round to

thee, and of nations and peoples; and herds of camels shall come to thee, and the

camels of Midian and Ephah shall cover thee: all from Saba shall come bearing gold, and shall bring frankincense, and they shall publish the salvation of the Lord. And all

the flocks of Kedar shall be gathered, and the rams of Nebaioth shall come; and

acceptable sacrifices shall be offered on my altar, and my house of prayer shall be

glorified. Who are these that fly as clouds, and as doves with young ones to me? The

isles have waited for me, and the ships of Tarshish among the first, to bring thy

children from afar, and their silver and their gold with them, and that for the sake of

the holy name of the Lord, and because the Holy One of Israel is glorified. And

strangers shall build thy walls, and their kings shall wait upon thee: for by reason of

my wrath I smote thee, and by reason of mercy I loved thee. And thy gates shall be

opened continually; they shall not be shut day nor night; to bring in to thee the power

of the Gentiles, and their kings as captives. For the nations and the kings which will

not serve thee shall perish; and those nations shall be made utterly desolate. And the

glory of Lebanon shall come to thee, with the cypress, and pine, and cedar together,

to glorify my holy place. And the sons of them that afflicted thee, and of them that

provoked thee, shall come to thee in fear; and thou shalt be called Zion, the city of the

Holy One of Israel. Because thou hast become desolate and hated, and there was no

helper, therefore I will make thee a perpetual gladness, a joy of many generations.

And thou shalt suck the milk of the Gentiles, and shalt eat the wealth of kings: and

shalt know that I am the Lord that saves thee and delivers thee, the Holy One of
Israel."
