A sound of going - "When thou shalt hear the sound of the angels coming to thy assistance, then go out to battle; for an angel is sent from the presence of God, that he may render thy way prosperous." - T.
for God is gone forth before thee--"a sound of going in the tops of the mulberry trees," that is, the rustling of the leaves by a strong breeze suddenly rising, was the sign by which David was divinely apprised of the precise moment for the attack.
