'Horns' in the Bible

Seven priests shall bear seven trumpets of rams' horns before the ark. On the seventh day, you shall march around the city seven times, and the priests shall blow the trumpets.

Joshua the son of Nun called the priests, and said to them, "Take up the ark of the covenant, and let seven priests bear seven trumpets of rams' horns before the ark of Yahweh."

It was so, that when Joshua had spoken to the people, the seven priests bearing the seven trumpets of rams' horns before Yahweh advanced, and blew the trumpets; and the ark of the covenant of Yahweh followed them.

The seven priests bearing the seven trumpets of rams' horns before the ark of Yahweh went on continually, and blew the trumpets: and the armed men went before them. The rear guard came after the ark of Yahweh. The trumpets sounded as they went.
