That's why God is on our side and will lead us into battle when the priests sound the signal on the trumpets. It's no use, Israelites. You might as well give up. There's no way you can defeat the LORD, the God your ancestors worshipped.
Moses sent them off to war. Phinehas the son of Eleazar went with them and took along some things from the sacred tent and the trumpets for sounding the battle signal.
If you have to go to war, you may find yourselves facing an enemy army that is bigger than yours and that has horses and chariots. But don't be afraid! The LORD your God rescued you from Egypt, and he will help you fight.
