Deuteronomy 20:1-3

1“When you go out to battle against your enemies and see 1horses and chariots and people more numerous than you, 2do not be afraid of them; for the Lord your God, who brought you up from the land of Egypt, is with you.

2When you are approaching the battle, the priest shall come near and speak to the people.

3He shall say to them, ‘Hear, O Israel, you are approaching the battle against your enemies today. Do not be fainthearted. 3Do not be afraid, or panic, or tremble before them,
