Old Testament Testifies That Jesus is God

Yahweh was pierced

Speaking of the end times in Zechariah 12:10 Jehovah (the LORD) said that in the future they would look on "ME" the one they had pierced. The hands and feet of Jesus were pierced when he was crucified.

The child will be called “Mighty God”

Prophesied a child would be born who would be called among other things, Mighty God, and Everlasting Father, that is, Father of Eternity. This also said He would rule forever over David's throne and kingdom. Fulfilled in Jesus. Matthew 1:1,18-25 John 1:1-3,14 John 5:18 John 8:58-59 John 10:30-33 John 20:28.

​The One from Bethlehem is from ancient times

Micah 5:1-2 (NIV) Marshal your troops, O city of troops, for a siege is laid against us. They will strike Israel's ruler on the cheek with a rod. 2 "But you, Bethlehem Ephrathah, though you are small among the clans of Judah, out of you will come for me one who will be ruler over Israel, whose origins are from of old, from ancient times."

(Mat 2:1-2 NIV)  After Jesus was born in Bethlehem in Judea, during the time of King Herod, Magi from the east came to Jerusalem {2} and asked, "Where is the one who has been born king of the Jews? We saw his star in the east and have come to worship him."

John 8:58 (NIV) "I tell you the truth," Jesus answered, "before Abraham was born, I am!"

Jesus will be called “God with us”

Isaiah 7:14 (NIV) 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.

Matthew 1:18-2:1 (NIV) 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. 19 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. 20 But after he had considered this, an angel of the Lord appeared to him in a dream and said, "Joseph son of David, do not be afraid to take Mary home as your wife, because what is conceived in her is from the Holy Spirit. 21 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." 22 All this took place to fulfill what the Lord had said through the prophet: 23 "The virgin will be with child and will give birth to a son, and they will call him Immanuel" --which means, "God with us." 24 When Joseph woke up, he did what the angel of the Lord had commanded him and took Mary home as his wife. 25 But he had no union with her until she gave birth to a son. And he gave him the name Jesus. 2:1 After Jesus was born in Bethlehem in Judea, during the time of King Herod, Magi from the east came to Jerusalem
