'Do Not Be Afraid' in the Bible

and he said, “Listen carefully, all Judah and you inhabitants of Jerusalem, and King Jehoshaphat. This is what the Lord says: ‘Do not be afraid or discouraged because of this vast number, for the battle is not yours, but God’s.

You do not have to fight this battle. Position yourselves, stand still, and see the salvation of the Lord. He is with you, Judah and Jerusalem. Do not be afraid or discouraged. Tomorrow, go out to face them, for Yahweh is with you.’”
