Joshua 6:8-10

8After Joshua spoke to the people, the seven priests with the rams’ horns started marching in the presence of the Lord, blowing the horns as they marched. And the Ark of the Lord’s Covenant followed behind them.

9Some of the armed men marched in front of the priests with the horns and some behind the Ark, with the priests continually blowing the horns.

10“Do not shout; do not even talk,” Joshua commanded. “Not a single word from any of you until I tell you to shout. Then shout!”
