Shevuot 38A

אלא מהא ליכא למשמע מינה.

Rather, no inference is to be learned from the Mishnah.

שבועת הפקדון כיצד? ״תן לי פקדון שיש לי בידך״ כו׳. תנו רבנן: כלל ⁠– אינו חייב אלא אחת. פרט ⁠– חייב על כל אחת ואחת. דברי רבי מאיר. רבי יהודה אומר: ״שבועה לא לך ולא לך ולא לך״⁠ – חייב על כל אחת ואחת.

§ The Mishnah teaches: What is the case of an oath on a deposit? It is where the claimant said to the defendant: Give me my deposit, which is in your possession, and the defendant replied: On my oath nothing of yours is in my possession, or the defendant said to him: Nothing of yours is in my possession; the claimant responded: I administer an oath to you, and the defendant said: Amen. In either case this defendant is liable to bring a guilt-offering if he lied. The Mishnah then discusses a case where 5 people sued him and he took an oath denying all of their claims. With regard to this case, A baraita states: If he included all the denials in one oath, he is liable for only one false oath; if he specified them, he is liable for his oath concerning each and every claim; this is the statement of R' Meir. R' Yehuda says that if he said: On my oath nothing of yours is in my possession, and nothing of yours, and nothing of yours, he is liable for his oath concerning each and every claim.

רבי אליעזר אומר: ״לא לך ולא לך ולא לך, שבועה״⁠ – חייב על כל אחת ואחת. רבי שמעון אומר: עד שיאמר שבועה לכל אחת ואחת.

The baraita continues: R' Eliezer says that only if he said: Nothing of yours is in my possession, and nothing of yours, and nothing of yours, on my oath, i.e., he said the word oath at the end, is he liable for his oath concerning each and every claim. R' Shimon says: He is not liable for his oath concerning each individual claim unless he says: On my oath, to each and every claimant.
