2 Chronicles 20:12, 15, 17, 20-21

You are our God! Punish them, for we are helpless in the face of this large army that is attacking us. We do not know what to do, but we look to you for help.”

Jahaziel said, “Your Majesty and all you people of Judah and Jerusalem, the LORD says that you must not be discouraged or be afraid to face this large army. The battle depends on God, not on you.

You will not have to fight this battle. Just take up your positions and wait; you will see the LORD give you victory. People of Judah and Jerusalem, do not hesitate or be afraid. Go out to battle, and the LORD will be with you!”

Early the next morning the people went out to the wild country near Tekoa. As they were starting out, Jehoshaphat addressed them with these words: “People of Judah and Jerusalem! Put your trust in the LORD your God, and you will stand firm. Believe what his prophets tell you, and you will succeed.” After consulting with the people, the king ordered some musicians to put on the robes they wore on sacred occasions and to march ahead of the army, singing: “Praise the LORD! His love is eternal!”
