Bava Batra 172B

אמר רב הונא: ״ממך״⁠ – אפילו מריש גלותא, ואפילו משבור מלכא.

Rav Huna said: The term: From you, in the document does not identify anyone in particular, and can mean even: From the Exilarch, or even: From King Shapur.

אמר ליה רב חסדא לרבה: פוק עיין בה, דלאורתא בעי לה רב הונא מינך.

Rav Ḥisda said to Rabba: Go out and investigate this matter, as tonight Rav Huna will ask this question of you.

נפק דק ואשכח ⁠– דתניא: גט שיש עליו עדים ואין בו זמן, אבא שאול אומר: אם כתוב בו ״גרשתיה היום״⁠ – כשר.

Rabba went out, examined the matter, and discovered a relevant source. As it is taught in a baraita: Concerning a bill of divorce in which there are the signatures of witnesses on the document but there is no date written on it, Abba Shaul says that if it is written in it: I divorced her today, it is valid.

אלמא ״היום״⁠ – ההוא יומא דנפיק ביה משמע; הכא נמי, ממך ⁠– מההוא גברא דנפיק מתותי ידיה משמע.

Rabba concludes: Apparently, the term: Today, indicates that day on which the bill of divorce emerges in the presence of the court. Here too, the term: From you, in a promissory note indicates that man from whose possession it emerges.

אמר ליה אביי: ודלמא אבא שאול כרבי אליעזר סבירא ליה, דאמר: עדי מסירה כרתי; אבל הכא ליחוש לנפילה!

Abaye said to him: But this is not a valid proof, as perhaps Abba Shaul holds in accordance with the opinion of R' Eliezer, who says that witnesses of the transmission of the bill of divorce effect the divorce. But here, let there be a concern for the possibility of the promissory note falling from its rightful owner and being found by the present holder of the document.
