The Apostle John, stayed with Jesus through it all, and now in Heaven with Jesus, and Antipas. Who? And the O.T. Saints. When? A Great Cloud of Witness. *

Matthew 4:21. And going on from there, He saw two other brothers, James the son of Zebedee, and John his brother, in the boat with Zebedee their father, mending their nets. And He called them, 22. and immediately they left the boat and their father, and followed Him.

Luke 9:53.  But they did not receive Him, because His face was set for the journey to Jerusalem. 54. And when His disciples James and John saw this, they said, "Lord, do You want us to command fire to come down from heaven and consume them, just as Elijah did?'

'

John 18:15. And Simon Peter followed Jesus, and so did another disciple. Now that disciple was known to the high priest, and went with Jesus into the courtyard of the high priest. 16. But Peter stood at the door outside. Then the other disciple, who was known to the high priest, went out and spoke to her who kept the door, and brought Peter in. 17. Then the servant girl who kept the door said to Peter, "You are not also one of this Man's disciples, are you?'' He said, "I am not.''

 John 19:25. Now there stood by the cross of Jesus His mother, and His mother's sister, Mary the wife of Clopas, and Mary Magdalene. 26.  When Jesus therefore saw His mother, and the disciple whom He loved standing by, He said to His mother, "Woman, behold your son!'' 27.  Then He said to the disciple, "Behold your mother!'' And from that hour that disciple took her to his own home.

Matthew 27:51. And behold, the veil of the temple was torn in two from top to bottom; and the earth quaked, and the rocks were split, 52. and the graves were opened; and many bodies of the saints who had fallen asleep were raised; 53. and coming out of the graves after His resurrection, they went into the holy city and appeared to many.

John 20:8. Then the other disciple, who came to the tomb first, went in also; and he saw and believed. 9.  For as yet they did not know the Scripture, that He must rise again from the dead.

Acts 1:9. Now when He had spoken these things, while they watched, He was taken up, and a * cloud received Him out of their sight.

Revelation 1:9.  I, John, both your brother and companion in tribulation, and in the kingdom and patience of Jesus Christ, was on the island that is called Patmos for the word of God and for the testimony of Jesus Christ.

Revelation 10:10.  And I took the little book out of the angel's hand and ate it, and it was as sweet as honey in my mouth. But when I had eaten it, my stomach became bitter. 11. And he said to me, "You must prophesy again about many peoples, nations, tongues, and kings.'' >>>

Revelation 11:1. Then I was given a reed like a measuring rod. And the angel stood, saying, "Rise and measure the temple of God, the altar, and those who worship there. 2. "But leave out the court which is outside the temple, and do not measure it, for it has been given to the Gentiles. And they will tread the holy city under foot for forty-two months. 3. "And I will give power to my two witnesses, and they will prophesy one thousand two hundred and sixty days, clothed in sackcloth.'' 4. These are the two olive trees and the two lampstands standing before the God of the earth.  5. And if anyone wants to harm them, fire proceeds from their mouth and devours their enemies. And if anyone wants to harm them, he must be killed in this manner. 6. These have power to shut heaven, so that no rain falls in the days of their prophecy; and they have power over waters to turn them to blood, and to strike the earth with all plagues, as often as they desire. 7. Now when they finish their testimony, the beast that ascends out of the bottomless pit will make war against them, overcome them, and kill them. 8. And their dead bodies will lie in the street of the great city which spiritually is called Sodom and Egypt, where also our Lord was crucified. 9. Then those from the peoples, tribes, tongues, and nations will see their dead bodies three and a half days, and not allow their dead bodies to be put into graves. 10. And those who dwell on the earth will rejoice over them, make merry, and send gifts to one another, because these two prophets tormented those who dwell on the earth. 11. Now after the three and a half days the breath of life from God entered them, and they stood on their feet, and great fear fell on those who saw them.  12.  And they heard a loud voice from heaven saying to them, "Come up here.'' And they ascended to heaven in a cloud, and their enemies saw them.

John the first, the second witness? My guess:

Revelation 2:13. "I know your works, and where you dwell, where Satan's throne is. And you hold fast to My name, and did not deny My faith even in the days in which Antipas was My faithful martyr, who was killed among you, where Satan dwells. 

Ussher’s Annals:

4070a AM, 4779 JP, 66 AD

6940. During the feast of tabernacles, after Cestius Gallus had burned Lydda, he marched toward Jerusalem. About seven or eight miles from there, the men of Jerusalem met him and fought a perilous battle near Bethhoron. When fresh troops arrived for Cestius, he forced the Jews into Jerusalem. On the 4th of the month of Hyperberetaios, (Niese: October 17th, Capellus: October 4th), he broke in and captured the lower part of the city (also known as Bezetha, or the New City and the Timber Market.) Then he attacked the temple and the upper city. He would easily have taken it, had he continued the attack more valiantly, for most of the people favoured the Romans and only the seditious men opposed them. {*Josephus, Jewish War, l. 2. c. 19. s. 1-4. (513-532) 2:521-529} [E900]

6941. When Cestius had almost captured the temple, he raised the siege for no good reason and retreated to Antipatris. Many of the Romans and auxiliary soldiers died on this march who were killed by the pursuing Jews. In their flight, the Romans abandoned most of their baggage, ammunition, engines, slings and other arms. The Jews later made good use of this equipment in their own defence against the siege of Titus. This humiliating retreat happened on the 8th of the month of Dios (Niese: November 25th, Capellus: November 8th) in the twelfth year of Nero. (That is, the twelfth year was over.) The thirteenth year of Nero had begun on the 13th of the previous October. {*Josephus, Jewish War, l. 2. c. 19. s. 5-9. (533-555) 2:529-537}

4071a AM, 4780 JP, 67 AD

6954. Meanwhile there was a great dissention throughout all Judea. Some wanted to continue the war, while others wanted to remain under the protection of the Romans. As a result, whole troops of thieves were gathered together all over Judea, who plundered those wanting peace. Laden with their plunder, they were received into Jerusalem, where they spread murders, dissensions, discords and rapines abroad. First, they imprisoned Antipas, together with a great many noblemen and the chief men of the city. Soon after that, they killed them without any trial, having falsely accused them of intending to surrender the city to the Romans.

4073b AM, 4783 JP, 70 AD 6978. Jerusalem was destroyed on a Saturday. {*Dio, l. 65. (7) 8:271}
