Charles Spurgeon Commentary 2 Chronicles 20:19

"And the Levites, of the children of the Kohathites and of the children of the Korahites, stood up to praise Jehovah, the God of Israel, with an exceeding loud voice." — 2 Chronicles 20:19 (ASV)

Here, again, we seem to be carried by great waves of excitement and devotion. One moment we are sinking down in adoration, now all rising up to listen to the loud voice of God's priests and Levites.

But they have to wait for the next day.
