A shoot will come up from the stump of Jesse, from his roots a Branch will bear fruit. The Spirit of the Lord will rest on him -- the Spirit of wisdom and of understanding, the Spirit of counsel and of power, the Spirit of knowledge and of the fear of the Lord -- and he will delight in the fear of the Lord.

He will not judge by what he sees with his eyes, or decide by what he hears with his ears; but with righteousness he will judge the needy, with justice he will give decisions for the poor of the earth. He will strike the earth with the rod of his mouth; with the breath of his lips he will slay the wicked. Righteousness will be his belt and faithfulness the sash around his waist.

The wolf will live with the lamb,
the leopard will lie down with the goat,
The calf and the lion and the yearling together;
And a little child will lead them.
The cow will feed the bear, their young will lie down together,
And the lion will eat straw like the ox.
The infant will play near the hole of the cobra,
And the young child put his hand into the viper's nest.
They will neither harm nor destroy on all my holy mountain,
For the earth will be full of the knowledge of the Lord
As the waters cover the sea.

In that day the Root of Jesse will stand as a banner for the peoples; the nations will rally to him, and his place of rest will be glorious. Isaiah 11:1-10.

This is how the birth of Jesus Christ came about: His mother Mary was pledged to be married to Joseph, but before they came together, she was found to be with child through the Holy Spirit. Because Joseph her husband was a righteous man and did not want to expose her to public disgrace, he had in mind to divorce her quietly. But after he had considered this, an angel of the Lord appeared to him in a dream and said, "Jospeh son of David, do not be afraid to take Mary home was your wife, because what is conceived in her is from the Holy Spirit. She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins." All this took place to fulfill what the Lord had said through the prophet: "The virgin will be with child and will give birth to a son, and they will call him Immanuel -- which means, 'God with us.'" When Joseph woke up, he did what the angel of the Lord had commanded him and took Mary home as his wife. But he had no union with her until she gave birth to a son. And he gave him the name Jesus. Matthew 1:18-25.

When they saw the star, they (the Magi) were overjoyed. On coming to the house, they saw the child with his mother Mary, and they bowed down and worshipped him. Then they opened their treasures and presented him with gifts of gold, and of incense and of myrrh. Matthew 2:10-11.

While they were there (Bethlehem), the time came for the baby to be born, and she gave birth to her firstborn, a son. She wrapped him in cloths and placed him in a manger, because there was no room for them at the inn. And there were shepherds living out in the fields nearby, keeping watch over their flocks at night. An angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were terrified. But the angel said to them, "Do not be afraid. I bring you good news of great joy that will be for all the people. Today in the town of David a Saviour has been born to you; he is Christ the Lord. This will be a sign to you: You will find a baby wrapped in cloths and lying in a manger." Suddenly a great company of the heavenly host appeared with the angel, praising God and saying, "Glory to God in the highest, and on earth peace to men on whom his favour rests." When the angels had left them and gone into heaven, the shepherds said to one another, "Let's go to Bethlehem and see this thing that has happened, which the Lord had told us about." So they hurried off and found Mary and Jospeh, and the baby, who was lying in the manger. When they had seen him, they spread the word concerning what had been told them about this child, and all who heard it were amazed at what the shepherds said to them. But Mary treasured up all these things and pondered them in her heart. The shepherds returned, glorifying and praising God for all the things they had heard and seen, which were just as they had been told. Luke 2:6-20

Therefore the Lord himself will give you a sign: The virgin will be with child and will give birth to a son, and will call him Immanuel. Isaiah 7:14

For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. Of the increase of his government and peace there will be no end. Isaiah 9:6-7a
