17 You won't even need to fight this battle! Just take your positions, Y'hudah and Yerushalayim, stand still, and watch how ADONAI will deliver you! Don't be afraid or distressed; tomorrow, go out against them; for ADONAI is with you.'"

19 and the L'vi'im from the descendants of the K'hati and the descendants of the Korchi, stood up and praised ADONAI the God of Isra'el at the top of their voices.

20 The next morning, they rose early and went out into the T'koa Desert. As they left, Y'hoshafat stood and said, "Listen to me, Y'hudah and you inhabitants of Yerushalayim! "Trust in ADONAI your God, and you will be safe. Trust in his prophets, and you will succeed."

21 After consulting with the people, he appointed those who would sing to ADONAI and praise the splendor of his holiness as they went out ahead of the army, saying, "Give thanks to ADONAI, for his grace continues forever."
