According to Jastrow, the word chaveir refers, sometimes to "associate, friend, partner (in sacrifices); colleague, fellow-student; fellow-being; of the same kind(also of things)" (via Sefaria).
Because of this range of possibilities, the talmudic use of "chaveir" might be a statement of friendship or simple generic similarity.
Are there uses of the word in the gemara which indicate "friend, to the exclusion of other people" or at least "someone known and specifically NOT just anyone else in a category"?
I'm trying to understand the phrase in Masechet Avodah Zara (43a) "שלו ומשל חברו" his and his friend's and seeing if it can be exclusionary -- that is, his and his actual/known friend's as opposed to "his and anyone else's".
Does anyone know of a use of chaveir in the gemara which points only to "friends"?
