Part of the Old Testament that shows pity (4)
I believe the answer is:
ruth
I believe this is a double definition.
'part of the old testament' is the first definition.
(I know that Ruth is part of Old Testament)
'pity' is the second definition.
(as opposed to ruthlessness)
'that shows' acts as a link.
(Other definitions for ruth that I've seen before include "Girl's name; grief" , "Remorse in Book of Bible?" , "OT female, book about her" , "once felt for a Moabite woman" , "she married Boaz!" .)
