Verse 10: And Joshua had commanded the people, saying, Ye shall not shout, nor make any noise with your voice (Heb. make your voice to be heard), neither shall any word proceed out of your mouth, until the day I bid you shout; then shall ye shout.
[Ye shall not shout] He orders the people to be silent in every way; 1. so that they might attentively listen to the voice of God, speaking, as it were, and bringing help: For this was signified by the sounding, Numbers 10:9. God willed that they return to the memory of those promises, and that they contemplate those in their soul, and rest in those believingly. And certainly to be silent sometimes signifies to rest in the grace and goodness of God, Psalm 4:4; 131:2; Lamentations 3:26. 2. Lest they should think that their noise and shouting contributed anything to the victory (Masius).
Ye shall not shout; because shouting before the time appointed would be ineffectual, and so might give them some discouragement, and their enemies matter of insulting.
