Courage, in facing enemies

In the OT, courage is shown principally in the leading of God's people against their enemies.

God commands his people to be courageous

Joshua 1:6–9 The LORD to Joshua as he was about to lead the Israelites into Canaan. See also Joshua 1:18, Joshua 8:1, Joshua 10:8; Judges 7:9–11; 2 Chronicles 20:15, 2 Chronicles 20:17

Be strong and courageous, for you shall give these people the inheritance of the land that I swore to their fathers I would give them. Above all, be strong and very courageous. Be careful to observe all the law that My servant Moses commanded you. Do not turn from it to the right or to the left, so that you may prosper wherever you go. This Book of the Law must not depart from your mouth; meditate on it day and night, so that you may be careful to do everything written in it. For then you will prosper and succeed in all you do. Have I not commanded you to be strong and courageous? Do not be afraid; do not be discouraged, for the LORD your God is with you wherever you go.”
