God’s forbearance displayed around Biblical city (7)
I believe the answer is:
mercury
'god's' is the definition.
(Mercury is an example)
'forbearance displayed around biblical city' is the wordplay.
'forbearance' becomes 'mercy' (I've seen this in another clue).
'displayed around' indicates putting letters inside.
'biblical city' becomes 'Ur' (city in the Hebrew bible).
'mercy' placed around 'ur' is 'MERCURY'.
(Other definitions for mercury that I've seen before include "Messenger of the Gods, or a chemical element" , "Atomic number 80" , "Quicksilver" , "Planet next to the sun" , "Metal in thermometer or barometer" .)
