Ye shall not need to fight in this battle,.... Since the Lord would fight for them: set yourselves, stand ye still; present themselves they might, as if ready to engage; and keep their ground, not giving way in the least, but would have no need to strike a stroke: and see the salvation of the Lord with you; which he would work for them, see Exo 14:13, and Judah, and Jerusalem, fear not, nor be dismayed; which is repeated for the confirmation of them: tomorrow go out against them, for the Lord will be with you; to protect them, fight for them, and give them victory; the Targum is,"the Word of the Lord shall be your help.''
