Matthew 24:30-31; Revelation 19:11-12; Revelation 19:17-21

30 “Then will appear the sign of the Son of Man in heaven. And then all the peoples of the earthwill mourn when they see the Son of Man coming on the clouds of heaven, with power and great glory. 31 And he will send his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of the heavens to the other.
11 I saw heaven standing open and there before me was a white horse, whose rider is called Faithful and True. With justice he judges and wages war. 12 His eyes are like blazing fire, and on his head are many crowns. He has a name written on him that no one knows but he himself.
17 And I saw an angel standing in the sun, who cried in a loud voice to all the birds flying in midair, “Come, gather together for the great supper of God, 18 so that you may eat the flesh of kings, generals, and the mighty, of horses and their riders, and the flesh of all people, free and slave, great and small.” 19 Then I saw the beast and the kings of the earth and their armies gathered together to wage war against the rider on the horse and his army. 20 But the beast was captured, and with it the false prophet who had performed the signs on its behalf. With these signs he had deluded those who had received the mark of the beast and worshiped its image. The two of them were thrown alive into the fiery lake of burning sulfur. 21 The rest were killed with the sword coming out of the mouth of the rider on the horse, and all the birds gorged themselves on their flesh.
