Bava Batra 39A

ולמחר תבענא ליה בדינא״⁠ – הויא מחאה.

and tomorrow, i.e., in the future, I will bring a claim against him in court, it is a valid protest.

אמר ״לא תימרו ליה״, מאי? אמר רב זביד: הא קאמר ״לא תימרו ליה״! רב פפא אמר: לדידיה לא תימרו ליה, לאחריני אימרו להו ⁠– חברך חברא אית ליה, חברא דחברך חברא אית ליה.

If the one lodging a protest also said: Do not tell the possessor of the protest, what is the halakha? Rav Zevid said: It is not a valid protest, because isn’t he saying: Do not tell him? Therefore, word of the protest will not reach the possessor and it is meaningless. Rav Pappa disagreed and said that the owner merely meant: Do not tell him personally, but they, i.e. the witnesses, should tell others. In that case, word of the protest will reach the possessor, since your friend has a friend whom he tells about the protest, and your friend’s friend has a friend whom he tells about the protest; therefore, it is a valid protest.

אמרו ליה: ״לא אמרינן ליה״⁠ – אמר רב זביד: הא קא אמרו ליה ״לא אמרינן ליה״! רב פפא אמר: לדידיה לא אמרינן ליה, לאחריני אמרי להו ⁠– חברך חברא אית ליה, וחברא דחברך חברא אית ליה.

If the witnesses before whom the owner lodged the protest said to him: We are not going to tell the possessor about your protest, what is the halakha? Rav Zevid said: It is not a valid protest, and he has to lodge a protest before other witnesses, as are they not saying to him: We are not going to tell him about your protest? Rav Pappa disagreed and said that they merely meant: We are not going to tell him personally, but we are going to tell others. In that case, word of the protest will reach the possessor, since your friend has a friend whom he tells about the protest, and your friend’s friend has a friend whom he tells about the protest; therefore, it is a valid protest.
