'Blow the Trumpet' in the Bible

And seven priests shall bear seven trumpets of rams horns before the ark: and the seventh day ye shall compass the city seven times, and the priests shall blow the trumpets.

The armed men went before the priests who blew the trumpets, and the rear guard came after the ark, while they continued to blow the trumpets.

The seven priests carrying the seven trumpets of rams’ horns before the ark of the Lord went on continually, and blew the trumpets; and the armed men went before them and the rear guard came after the ark of the Lord, while they continued to blow the trumpets.
