Yoshua 6:10

Bali Yoshua alikuwa amewaagiza watu, “Msipige kelele ya vita, msipaze sauti zenu, wala kusema neno lolote mpaka siku ile nitakayowaambia mpige kelele. Ndipo mtapiga kelele!”

And Joshua had commanded the people, saying, Ye shall not shout, nor make any noise with your voice, neither shall any word proceed out of your mouth, until the day I bid you shout; then shall ye shout.
