Deut 20:1 When you go to war against your enemies and see horses and chariots and an army greater than yours, do not be afraid of them, because the LORD your God, who brought you up out of Egypt, will be with you.
2 When you are about to go into battle, the priest shall come forward and address the army.
3 He shall say: “Hear, O Israel, today you are going into battle against your enemies. Do not be fainthearted or afraid; do not be terrified or give way to panic before them.
4 For the LORD your God is the one who goes with you to fight for you against your enemies to give you victory.”
8 Then the officers shall add, “Is any man afraid or fainthearted? Let him go home so that his brothers will not become disheartened too.”
