Isaiah 27:13
[13]And it shall come to pass in that day, that the great trumpet shall be blown, and they shall come which were ready to perish in the land of Assyria, and the outcasts in the land of Egypt, and shall worship the LORD in the holy mount at Jerusalem.

1 Thessalonians 4:16
[16]For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:

2 Esdras 6:23-25
[23]And the trumpet shall give a sound, which when every man heareth, they shall be suddenly afraid.
[24]At that time shall friends fight one against another like enemies, and the earth shall stand in fear with those that dwell therein, the springs of the fountains shall stand still, and in three hours they shall not run.
[25]Whosoever remaineth from all these that I have told thee shall escape, and see my salvation, and the end of your world.

Matthew 24:29-31
[29]Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
[30]And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
[31]And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.

Luke 21:36
[36]Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.
