I’m seen with Bible forsaking large drink (6)
I believe the answer is:
imbibe
'drink' is the definition.
('imbibe' can be a synonym of 'drink')
'i'm seen with bible forsaking large' is the wordplay.
'seen with' means one lot of letters go next to another.
'forsaking' indicates named letters should be taken away.
'large' becomes 'l'.
'bible' with 'l' taken out is 'bibe'.
'im'+'bibe'='IMBIBE'
(Other definitions for imbibe that I've seen before include "Drink, take in" , "Partake of drink" , "Swallow" , "Drink in - assimilate" , "Take in (with one's mother's milk?)" .)
