Was it the rich man's literal tongue that was burning? Would literal drops of water soothe his tongue?
Time to recognize the account of Lazarus and the Rich Man is fictional.
My contention is that the literary form of Lazarus and the Rich Man is satire, or more particularly, a parody, there must be clear evidence that:
a. A common or "well known story line is being imitated".
b. irony is employed; that the story’s outcome is changed such that there is clear “incongruity between the actual result of a sequence of events and the expected result”
c. the unexpected results "highlight human stupidity" or corruption.
d. "a comic end is served", the purpose of which is to cause listeners "to detach sympathies from certain people (groups), to judge their actions and to see the absurdity in their behavior…
Satire can be defined as “biting wit, irony or sarcasm used to expose vice or folly...”.
And good satire never fails to inspire “laughter, contempt, or horror as it seeks to correct the follies and abuses it uncovers”.
