The primary function of messianic prophecies is to indicate and confirm who the Messiah is. However, God may be this type of prophecy for other reasons as well. Let's explore the messianic prophecies about the King!

1. Mary is told that Jesus fulfills God's promise of the King from the line of David who will reign forever (Luke 1:26-33). What divine covenant is this referring to and when was it made (2 Sam 7:12-16)? Also pertaining to the birth of Jesus, the Magi come looking for the King of the Jews (Matt 2:1-6). Who was the prophet of that messianic prophecy? How would you find out?

In the sixth month of Elizabeth's pregnancy, God sent the angel Gabriel to Nazareth, a town in Galilee, to a virgin pledged to be married to a man named Joseph, a descendant of David. The virgin's name was Mary. The angel went to her and said, "Greetings, you who are highly favored! The Lord is with you."
Mary was greatly troubled at his words and wondered what kind of greeting this might be. But the angel said to her, "Do not be afraid, Mary; you have found favor with God. You will conceive and give birth to a son, and you are to call him Jesus. He will be great and will be called the Son of the Most High. The Lord God will give him the throne of his father David, and he will reign over Jacob's descendants forever; his kingdom will never end." (Luke 1:26-33, NIV)

When your days are over and you rest with your ancestors, I will raise up your offspring to succeed you, your own flesh and blood, and I will establish his kingdom. He is the one who will build a house for my Name, and I will establish the throne of his kingdom forever. I will be his father, and he will be my son. When he does wrong, I will punish him with a rod wielded by men, with floggings inflicted by human hands. But my love will never be taken away from him, as I took it away from Saul, whom I removed from before you. Your house and your kingdom will endure forever before me; your throne will be established forever.'" (2 Sam 7:12-16, NIV)

After Jesus was born in Bethlehem in Judea, during the time of King Herod, Magi from the east came to Jerusalem and asked, "Where is the one who has been born king of the Jews? We saw his star when it rose and have come to worship him." When King Herod heard this he was disturbed, and all Jerusalem with him. When he had called together all the people's chief priests and teachers of the law, he asked them where the Messiah was to be born. "In Bethlehem in Judea," they replied, "for this is what the prophet has written:
"'But you, Bethlehem, in the land of Judah,
Are by no means least among the rulers of Judah;
For out of you will come a ruler
Who will shepherd my people Israel.'" (Matt 2:1-6, NIV)

2. Though He was designated as the descendant of David with eternal kingship by an angel, Jesus never cited a messianic prophecy explicitly confirming His kingship throughout His ministry. When does Jesus do so? How does He do so? What impact does this have on the Jews of Jerusalem?

As they approached Jerusalem and came to Bethphage on the Mount of Olives, Jesus sent two disciples, saying to them, "Go to the village ahead of you, and at once you will find a donkey tied there, with her colt by her. Untie them and bring them to me. If anyone says anything to you, say that the Lord needs them, and he will send them right away." This took place to fulfill what was spoken through the prophet:
"Say to Daughter Zion,
'See, your king comes to you,
Gentle and riding on a donkey,
and on a colt, the foal of a donkey.'" (Matt 21:1-5, NIV)

The next day the great crowd that had come for the festival heard that Jesus was on his way to Jerusalem. They took palm branches and went out to meet him, shouting,
"Hosanna!"
"Blessed is he who comes in the name of the Lord!"
"Blessed is the king of Israel!"
Jesus found a young donkey and sat on it, as it is written:
"Do not be afraid, Daughter Zion;
see, your king is coming,
seated on a donkey's colt." (John 12:12-15, NIV)

Rejoice greatly, Daughter Zion!
Shout, Daughter Jerusalem!
See, your king comes to you,
Righteous and victorious,
lowly and riding on a donkey,
on a colt, the foal of a donkey. (Zech 9:9, NIV)

3. At Jesus' trial before Jewish religious authorities, the chief priests and whole Jewish council of elders and scribes were unable to get enough evidence of blaspheme to convict Jesus. They were frustrated in their attempt to sentence Jesus to death. What do you observe of what Jesus says? What if Jesus did not cite these messianic prophecies?

The chief priests and the whole Sanhedrin were looking for false evidence against Jesus so that they could put him to death. But they did not find any, though many false witnesses came forward. Finally two came forward and declared, "This fellow said, 'I am able to destroy the temple of God and rebuild it in three days.'"
Then the high priest stood up and said to Jesus, "Are you not going to answer? What is this testimony that these men are bringing against you?" But Jesus remained silent.
The high priest said to him, "I charge you under oath by the living God: Tell us if you are the Messiah, the Son of God."
"You have said so," Jesus replied. "But I say to all of you: From now on you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven." (Matt 26:59-64, NIV)

The Lord says to my lord:
"Sit at my right hand
Until I make your enemies
A footstool for your feet." (Ps 110:1, NIV)

"In my vision at night I looked, and there before me was one like a son of man, coming with the clouds of heaven. He approached the Ancient of Days and was led into his presence. He was given authority, glory and sovereign power; all nations and peoples of every language worshiped him. His dominion is an everlasting dominion that will not pass away, and his kingdom is one that will never be destroyed. (Dan 7:13-14, NIV)
