Book of Moses: Exodus
"And it came to pass on the third day, as the morning drew nigh, there were voices and lightnings and a dark cloud on mount Sina: the voice of the trumpet sounded loud, and all the people in the camp trembled. And Moses led the people forth out of the camp to meet God, and they stood by under the mountain. The mount of Sina was altogether on a smoke, because God had descended upon it in fire; and the smoke went up as the smoke of a furnace, and the people were exceedingly amazed. And the sounds of the trumpet were waxing very much louder."
Book of Moses: Numbers
"And whenever ye shall gather the assembly, ye shall sound, but not an alarm. And the priests the sons of Aaron shall sound with the trumpets; and it shall be a perpetual ordinance for you throughout your generations. And if ye shall go forth to war in your land against your enemies that are opposed to you, then shall ye sound with the trumpets; and ye shall be had in remembrance before the Lord, and ye shall be saved from your enemies."
Prophecy of Joel
"Sound the trumpet in Sion, make a proclamation in my holy mountain, and let all the inhabitants of the land be confounded: for the day of the Lord is near"
Prophecy of Zephaniah
"For the great day of the Lord is near, it is near, and very speedy; the sound of the day of the Lord is made bitter and harsh. 15 A mighty day of wrath is that day, a day of affliction and distress, a day of desolation and destruction, a day of gloominess and darkness, a day of cloud and vapour, a day of the trumpet and cry against the strong cities, and against the high towers. And I will greatly afflict the men, and they shall walk as blind men, because they have sinned against the Lord"
The Good News according to Matthew
"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. 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."
First Letter of Paul to the Corinthians
"Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality."
The Book of Revelation
"After this I looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said, Come up hither, and I will shew thee things which must be hereafter. And immediately I was in the spirit: and, behold, a throne was set in heaven, and one sat on the throne."
The Book of Revelation
"And I saw the seven angels which stood before God; and to them were given seven trumpets."
