I am familiar with this rule:
1.Tell something to somebody
2. Say something
But what about his sentence from Melville's Bartleby Scrivener?
“I know you,” he said, without looking round,—“and I want nothing to say to you.”
To tell and
to say are very flexible in their usage. A rule of thumb: when you tell something, you are giving particular information, and when you say something, you are letting your opinion be known or sharing your thoughts.
These are all idiomatic:
Psssst! ... I have a secret to tell you!
Angry mother to disobedient teenage daughter:
Come downstairs this instant, young lady! I have something to say to you!
The locution Bartleby uses is somewhat archaic today. Bartleby is saying that he does not want to have anything to do with the person. He does not want to find himself in a situation where the two of them are conversing about anything.
