Joshua 6:8-10 Living Bible (TLB)
6-9 So Joshua summoned the priests and gave them their instructions: the armed men would lead the procession, followed by seven priests blowing continually on their trumpets. Behind them would come the priests carrying the Ark, followed by a rear guard.
10 “Let there be complete silence except for the trumpets,” Joshua commanded. “Not a single word from any of you until I tell you to shout; then shout!”
