Charles Spurgeon Commentary 2 Chronicles 20:1-3

"And it came to pass after this, that the children of Moab, and the children of Ammon, and with them some of the Ammonites, came against Jehoshaphat to battle. Then there came some that told Jehoshaphat, saying, There cometh a great multitude against thee from beyond the sea from Syria; and, behold, they are in Hazazon-tamar (the same is En-gedi). And Jehoshaphat feared, and set himself to seek unto Jehovah; and he proclaimed a fast throughout all Judah." — 2 Chronicles 20:1-3 (ASV)

It came to pass after this also, that the children of Moab, and the children of Ammon, and with them other beside the Ammonites, came against Jehoshaphat to battle. Then there came some that told Jehoshaphat, saying, There cometh a great multitude against thee from beyond the sea on this side Syria; and, behold, they be in Hazazontamar, which is Engedi. And Jehoshaphat feared, and set himself to seek the LORD, and proclaimed a fast throughout all Judah.

An angry God is to be sought. Even though he smites us, we must turn to him. It is from the hand that wields the rod that we are to expect deliverance, if it ever comes at all.
