Deuteronomy 20:4

For the Lord your God is he that goeth with you,.... To battle, and therefore they had no reason to fear and be dismayed, to be fainthearted, terrified, and tremble:

fear not, I am with thee,.... Isaiah 41:10, this, according to the Misnah f, respects the ark, and so Jarchi, which was a symbol of the divine Presence, and went with them to battle; see Joshua 6:4

to fight for you against your enemies, to save you; to annoy and destroy the one, and to protect and save the other; thus far the anointed priest addressed the people in an oration to this purpose: the account Maimonides gives of it is, that

"when they have set their ranks, and are near to a battle, the anointed of war stands on an high place, and all the ranks before him, and says to them in the holy tongue, "hear, O Israel", c. unto to save you and then another priest under him causes it to be heard by all the people with an high voice g;''

he repeated what the anointed of war had said, and expressed it with a loud voice, that all might hear.
