Lev 23:24 “Say to the Israelites: ‘On the first day of the seventh month you are to have a day of sabbath rest, a sacred assembly
commemorated with trumpet blasts.
Joel 2:1
Blow the trumpet in Zion; sound the alarm on my holy hill. Let all who live in the land tremble, for the day of the LORD is coming. It is close at hand--
Zeph 1:14-16 The great day of the Lord is near—near and coming quickly. The cry on the day of the Lord is bitter; the Mighty Warrior shouts his battle cry. 15That day will be a day of wrath—a day of distress and anguish, a day of trouble and ruin, a day of darkness and gloom, a day of clouds and blackness—16
a day of trumpet and battle cry against the fortified cities and against the corner towers.
Matt 24:29-31 “Immediately after the distress of those days “ ‘the sun will be darkened, and the moon will not give its light; the stars will fall from the sky, and the heavenly bodies will be shaken.’ 30“Then will appear the sign of the Son of Man in heaven. And then all the peoples of the earth will 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.
1 Cor 15:50-54 I declare to you, brothers and sisters, that flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable. 51Listen, I tell you a mystery: We will not all sleep, but we will all be changed— 52
in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed. 53For the perishable must clothe itself with the imperishable, and the mortal with immortality. 54When the perishable has been clothed with the imperishable, and the mortal with immortality, then the saying that is written will come true: “Death has been swallowed up in victory.”
1 Thess 4:13-17 Brothers and sisters, we do not want you to be uninformed about those who sleep in death, so that you do not grieve like the rest of mankind, who have no hope. 14For we believe that Jesus died and rose again, and so we believe that God will bring with Jesus those who have fallen asleep in him. 15According to the Lord’s word, we tell you that we who are still alive, who are left until the coming of the Lord, will certainly not precede those who have fallen asleep. 16For the Lord himself will come down from heaven, with a loud command,
with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first. 17After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever.
