Joshua 6:9-11

⁹And let the men of war proceed before, and the priests bringing up the rear behind the ark of the covenant of the Lord proceed sounding the trumpets.

¹⁰And Joshua commanded the people, saying, Cry not out, nor let any one hear your voice, until he himself declare to you the time to cry out, and then ye shall cry out.

¹¹And the ark of the covenant of God having gone round immediately returned into the camp, and lodged there.
