“Fools, because of their transgression,
And because of their iniquities, were afflicted. Their soul abhorred all manner of food, And they drew near to the gates of death. Then they cried out to the Lord in their trouble, And He saved them out of their distresses. He sent His word and healed them, And delivered them from their destructions. Oh, that men would give thanks to the Lord for His goodness, And for His wonderful works to the children of men! Let them sacrifice the sacrifices of thanksgiving, And declare His works with rejoicing.” – Psa. 107:17-22
These all go together to form a refrain like our modern hymns with their choruses.
