The great prayer of Judah (2 Chr 20:18-20:19)

“Then King Jehoshaphat bowed down with his face to the ground. All Judah and the inhabitants of Jerusalem fell down before Yahweh, worshiping Yahweh. The Levites, of the Kohathites and the Korahites, stood up to praise Yahweh, the God of Israel, with a very loud voice.”

The king and everyone present bowed down with their face to the ground, a lot like the Muslim prayer stance. They fell before Yahweh and worshipped him. Then the Levite singers, especially the Kohathites and Korahites, began to praise Yahweh with a loud voice.
