“But when He saw the multitudes, He was moved with compassion on them”

WHY DO WE STAND TO SING?

Then Jehoshaphat knelt down, bowing with his face to
the ground. All Judah and Jerusalem did the same,
worshiping GOD. The Levites (both Kohathites and
Korahites) stood to their feet to praise GOD, the God of
Israel; they praised at the top of their lungs!”
(Chron. 20:19)MSG
