Thanks for your question! There are actually many biblical passages which teach both the deity and humanity of Christ. I’ve listed just a few for your consideration.
1. Isaiah 9:6-7
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. He will reign on David’s throne and over his kingdom, establishing and upholding it with justice and righteousness from that time on and forever. The zeal of the LORD Almighty will accomplish this.
Note that the promised Messiah (or Christ) would be born as a son to Israel. He was thus a Man. At the same time, however, His name will be called Mighty God, etc. He is thus also God.
2. Micah 5:2-3 (quoted in Matt. 2:6)
“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.”
3 Therefore Israel will be abandoned until the time when she who is in labor gives birth and the rest of his brothers return to join the Israelites.
Again, Messiah is born of a woman (v. 3) to be ruler in Israel (v. 2). He is thus a Man. However, His goings forth are “from the days of eternity” (v. 2). He thus had no beginning and must therefore be God (Who alone is eternal).
3. John 1:1-3, 14
In the beginning was the Word, and the Word was with God, and the Word was God.
2 He was with God in the beginning.
3 Through him all things were made; without him nothing was made that has been made.
14 The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the One and Only, who came from the Father, full of grace and truth.
Notice that the Word is God (v. 1). Notice also that the Word became a human being (v. 14). Jesus is both God and Man.
4. Philippians 2:5-11
Your attitude should be the same as that of Christ Jesus:
6 Who, being in very nature God, did not consider equality with God something to be grasped,
7 but made himself nothing, taking the very nature of a servant, being made in human likeness.
8 And being found in appearance as a man, he humbled himself and became obedient to death–even death on a cross!
9 Therefore God exalted him to the highest place and gave him the name that is above every name,
10 that at the name of Jesus every knee should bow, in heaven and on earth and under the earth,
11 and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.
This is a classic passage on both the deity and humanity of Christ.
5. Colossians 1:13-23
For he has rescued us from the dominion of darkness and brought us into the kingdom of the Son he loves,
14 in whom we have redemption, the forgiveness of sins.
15 He is the image of the invisible God, the firstborn over all creation.
16 For by him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things were created by him and for him.
17 He is before all things, and in him all things hold together.
18 And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy.
19 For God was pleased to have all his fullness dwell in him,
20 and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross.
21 Once you were alienated from God and were enemies in your minds because of your evil behavior.
22 But now he has reconciled you by Christ’s physical body through death to present you holy in his sight, without blemish and free from accusation–
23 if you continue in your faith, established and firm, not moved from the hope held out in the gospel. This is the gospel that you heard and that has been proclaimed to every creature under heaven, and of which I, Paul, have become a servant.
Again, this passage strongly affirms both the deity (v. 19) and humanity (v. 22) of Jesus.
These are just a few passages which can be offered. Many passages, taken in isolation, affirm either the deity of Christ on the one hand, or His humanity on the other. When all this evidence is taken into account, it becomes clear that the Bible repeatedly affirms that Jesus was indeed the unique God-Man.
God bless you,
