Behold, God himself is with us for our captain Here in our camp. We may be sure he is with us, because we are with him. And as a token of his presence we have here with us his priests, sounding his trumpets According to the law, as a testimony against you, and an assurance to us, that in the day of battle we shall be remembered before the Lord our God, and saved from our enemies. See Numbers 10:9, where this sacred signal is thus explained. Nothing is so effectual to imbolden men, and give them courage and fortitude in the day of battle, as to have an assurance that God is with them, and fighteth for them. Fight ye not against the God of your fathers It is folly to fight against the God of almighty power; but it is treachery, and base ingratitude, to fight against your fathers' God, and you cannot expect to prosper. Thus he concludes with giving them fair warning.
