The Lord shall fight for you,.... By commanding the wind of the heavens, and the waves of the sea, and employing them against their enemies, and on their behalf; they being unarmed, and so not in a condition to fight for themselves, as well as they had no heart or spirit for it: and ye shall hold your peace; be still, and quiet, and easy in your minds, and forbear saying or doing anything; "be silent"; and neither express the fear and distress of their minds, by any mournful sounds, nor their joy of faith by shouts and huzzas; as they could not draw a sword, they were not so much as to blow a trumpet, and break a pitcher, and cry the sword of the Lord, and of Israel as they after did on another occasion, at least their posterity.
