The Sound of Singing Fills the Air

"God is good, His love endures forever" in Hebrew is the shortest song in the bible.
In 2 Chronicles when Solomon dedicated the temple to God, many musicians in the band played a fanfare on trumpets & other instruments, and as the crowd sang these words the temple was filled like a cloud with the glory of God.
Later in the book the song is used again after Jehoshaphat was told "You will not have to fight this battle ... Do not be afraid ... The Lord will be with you."
