Pity its only part of the Old Testament (4)
I believe the answer is:
ruth
This clue might be a double definition.
'pity' is the first definition.
(as opposed to ruthlessness)
'part of the old testament' is the second definition.
(I know this)
'its only' is the link.
I am not very happy about this link. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for ruth that I've seen before include "condolences?" , "Old word for pity, or Bible book" , "Lady" , "she married Boaz!" , "Biblical character" .)
