ב בשלמא לרבנן מנינא למעוטי הא דרבי מאיר אלא לר' מאיר מנינא למעוטי מאי
2 We can understand the Rabbis [specifying the number] three, [because they desired] to except the point stated by R. Meir. But what did R. Meir desire to except by specifying the number [four]? — [He desired] to except the following case which has been taught: If the witnesses are not able to sign their names, we make dents on the sheet and they fill them in with ink. Rabban Simeon b. Gamaliel says: This applies only to writs of divorce. With writs of emancipation and all other documents, if the witnesses are able to read and to sign their names, they sign, and if not, they do not sign. How does 'reading' come in here? — There is something omitted, and the passage should run thus: 'If the witnesses cannot read, the document is read to them and they then sign, and if they are unable to sign, dents are made for them.'
