'Horns' in the Bible

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

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

{And when Joshua spoke} to the people, the seven priests carrying the seven trumpets of rams' horns before the presence of Yahweh went forward and they blew the trumpets; and the ark of the covenant of Yahweh followed behind them.

The seven priests carrying the seven trumpets of the rams' horns before the ark of Yahweh went on continually, and they blew on the trumpets. And the armed [men] went before them, and [the] rear guard came after the ark of Yahweh, while the trumpets blew continually.
