And when Judah looked back,.... On hearing a noise behind them: behold, the battle was before and behind; men were set in battle array, and the battle was begun, and an attack made upon them both ways: and they cried unto the Lord; for help against their enemies, and to deliver them out of their hands: and the priests sounded with the trumpets; to inspire them with cheerfulness, and to suggest to them that God was with them and they need not be afraid.
