“And it came to pass, when Joshua had spoken unto the people, that the seven priests bearing the seven trumpets of rams' horns passed on before the LORD, and blew with the trumpets: and the ark of the covenant of the LORD followed them.”
King James Version (KJV)
6:6 Of rams horns - Of the basest matter, and the dullest sound, that the excellency of the power might be of God.
6:7 Him that is armed - God would have them armed both for the defense of themselves and the ark, in case the enemies should make a sally upon them, and for the execution of the Lord's vengeance upon that city.
6:9 The rereward - Which being opposed to the armed men, may seem to note the unarmed people, who were desirous to be spectators of this wonderful work.
6:10 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.
