φρέαρ [1 verse](noun sg neut acc) "A pit" is from phrear, which means "an artificial well", "tank", "cistern", and "reservoir". Metaphorically, it means "a brink" or "a large wine-cup". -- The Greek word, used by Jesus only here, translated as "a pit" means "an artificial well" or "reservoir". Metaphorically, it means "a brink" or "a large wine-cup". It is a completely different word than the word used in Matthew, which means a "pit" or "well" but comes from the word for "deep".
