Revelation 1:1-3

1 The revelation from Jesus Christ, which God gave Him to show His servants what must soon take place. He made it known by sending his angel to his servant John, ² who testifies to everything he saw—that is, the word of God and the testimony of Jesus Christ. ³ Blessed is the one who reads aloud the words of this prophecy, and blessed are those who hear it and take to heart what is written in it, because the time is near.

Revelation 1:4-6

 ⁴ John to the seven churches which are in Asia: Grace be unto you, and peace, from him which is, and which was, and which is to come; and from the seven Spirits which are before his throne;

⁵ And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood,

⁶ And hath made us kings and priests unto God and his Father; to him be glory and dominion for ever and ever. Amen.

Revelation 1:7-9

 ⁷ “Look, he is coming with the clouds,”
    and “every eye will see him,
even those who pierced him”;
    and all peoples on earth “will mourn because of him.”
So shall it be! Amen.

⁸ “I am the Alpha and the Omega,” says the Lord God, “who is, and who was, and who is to come, the Almighty.”

⁹ I, John, your brother and companion in the suffering and kingdom and patient endurance that are ours in Jesus, was on the island of Patmos because of the word of God and the testimony of Jesus

Revelation 1:10 -13

¹⁰ On the Lord’s Day I was in the Spirit, and I heard behind me a loud voice like a trumpet, ¹¹ which said: “Write on a scroll what you see and send it to the seven churches: to Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia and Laodicea.” ¹² I turned around to see the voice that was speaking to me. And when I turned I saw seven golden lampstands, ¹³ and among the lampstands was someone like a son of man, dressed in a robe reaching down to his feet and with a golden sash around his chest.

Revelation 1: 17-18

^{17 "}When I saw him, I fell at his feet as though dead. Then he placed his right hand on me and said: “Do not be afraid. I am the First and the Last. ¹⁸ I am the Living One; I was dead, and now look, I am alive for ever and ever! And I hold the keys of death and Hades." 

One can only imagine the feeling John must have had at this point being confronted with all this overwhelming sound and imagery, but Christ is quick to comfort him and tell him not to be afraid.

Revelation 1:19-20

¹⁹ “Write, therefore, what you have seen, what is now and what will take place later. ²⁰ The mystery of the seven stars that you saw in my right hand and of the seven golden lampstands is this: The seven stars are the angels of the seven churches, and the seven lampstands are the seven churches."

In these verses Jesus makes it clear what the seven lampstands and the seven angels were referring to earlier. One source I found suggested that the word angel could also be translated as messenger, so that the verse may reference human pastors or disciples. 

Revelation 2: 1-6

“To the angel of the church in Ephesus, write:

These are the words of him who holds the seven stars in his right hand and walks among the seven golden lampstands. ² I know your deeds, your hard work and your perseverance. I know that you cannot tolerate wicked people, that you have tested those who claim to be apostles but are not, and have found them false. ³ You have persevered and have endured hardships for my name, and have not grown weary.

⁴ Yet I hold this against you: You have forsaken the love you had at first. ⁵ Consider how far you have fallen! Repent and do the things you did at first. If you do not repent, I will come to you and remove your lampstand from its place. ⁶ But you have this in your favor: You hate the practices of the Nicolaitans, which I also hate."

Revelation 2: 18-21

 ¹⁸ “To the angel of the church in Thyatira write:

These are the words of the Son of God, whose eyes are like blazing fire and whose feet are like burnished bronze. ¹⁹ I know your deeds, your love and faith, your service and perseverance, and that you are now doing more than you did at first.

²⁰ Nevertheless, I have this against you: You tolerate the woman Jezebel, who calls herself a prophet. By her teaching she misleads my servants into sexual immorality and the eating of food sacrificed to idols. ²¹ I have given her time to repent of her immorality, but she is unwilling.

Revelation 4:1-3

  

 "After this I looked, and there before me was a door standing open in heaven. And the voice I had first heard speaking to me like a trumpet said, “Come up here, and I will show you what must take place after this.” ² At once I was in the Spirit, and there before me was a throne in heaven with someone sitting on it. ³ And the one who sat there had the appearance of jasper and ruby. A rainbow that shone like an emerald encircled the throne."

 

Revelation 7: 1-8

 

"After this I saw four angels standing at the four corners of the earth, holding back the four winds of the earth so that no wind could blow on earth or sea or against any tree.  I saw another angel ascending from the rising of the sun, having the seal of the living God, and he called with a loud voice to the four angels who had been given power to damage earth and sea,  saying, “Do not damage the earth or the sea or the trees, until we have marked the servants of our God with a seal on their foreheads.”

 And I heard the number of those who were sealed, one hundred forty-four thousand, sealed out of every tribe of the people of Israel:

From the tribe of Judah twelve thousand sealed,
from the tribe of Reuben twelve thousand,
from the tribe of Gad twelve thousand,from the tribe of Asher twelve thousand,
from the tribe of Naphtali twelve thousand,
from the tribe of Manasseh twelve thousand from the tribe of Simeon twelve thousand,
from the tribe of Levi twelve thousand,
from the tribe of Issachar twelve thousand, 

from the tribe of Zebulun twelve thousand,
from the tribe of Joseph twelve thousand,
from the tribe of Benjamin twelve thousand sealed."

Revelation 10:11

 ¹¹ Then they said to me, “You must prophesy again about many peoples and nations and languages and kings.”

 

Revelation 11:9-10

  ⁹ For three and a half days members of the peoples and tribes and languages and nations will gaze at their dead bodies and refuse to let them be placed in a tomb; ¹⁰ and the inhabitants of the earth will gloat over them and celebrate and exchange presents, because these two prophets had been a torment to the inhabitants of the earth.
