17 Ye shall not need to fight in this; take up your battle positions, stand ye firm, and see the Yeshuat Hashem with you, O Yehudah and Yerushalayim. Fear not, nor be dismayed; makhar (tomorrow) go out against them, for Hashem will be with you.

Divrey Hayamim Bais 20:17 Meaning and Commentary

2 Chronicles 20:17

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 ( Exodus 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.''
