2 Chronicles 20:17-18

17You will not have to fight this battle. Take up your positions; stand firm and see the deliverance the LORD will give you, Judah and Jerusalem. Do not be afraid; do not be discouraged. Go out to face them tomorrow, and the LORD will be with you.’ ” 18Jehoshaphat bowed down with his face to the ground, and all the people of Judah and Jerusalem fell down in worship before the LORD .
