Joshua 6:4-6

New Catholic Bible

⁴ Seven priests will carry seven trumpets made from ram’s horns in front of the Ark. On the seventh day you are to march around the city seven times while the priests blow their trumpets.^{[a] 5} Then they will make a long blast on the ram’s horns. As soon as you hear the sound of the trumpet, have all of the people give a great shout. The walls will fall down, and the people will go on up, every man in a straight line.”

⁶ So Joshua, the son of Nun, summoned the priests and said to them, “Take up the Ark of the Covenant. Have seven priests holding trumpets made from rams’ horns precede the Ark of the Lord.”
