TSK · Judges 7:8

"Speak to the children of Israel, saying, 'In the seventh month, on the first day of the month, shall be a solemn rest to you, a memorial of blowing of trumpets, a holy convocation.

When you go to war in your land against the adversary who oppresses you, then you shall sound an alarm with the trumpets. Then you will be remembered before Yahweh your God, and you will be saved from your enemies.

So the people shouted, and the priests blew the trumpets. It happened, when the people heard the sound of the trumpet, that the people shouted with a great shout, and the wall fell down flat, so that the people went up into the city, every man straight before him, and they took the city.

Then all the Midianites and the Amalekites and the children of the east assembled themselves together; and they passed over, and encamped in the valley of Jezreel.

in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we will be changed.
