The rule
כל מקום שנאמר ״ויהי״ אינו אלא לשון צער.
Wherever it says “vayehi”, the verse signals distress.
The Gemara brings many verses as proof, including “in the days of Achashverosh” - days of Haman's decree.
Then the Gemara challenges with verses where “vayehi” describes joy, and refines the rule.
- 1Read the proposed rule
- 2Test proofs and objections
- 3Distinguish vayehi from vayehi bimei
Rav Ashi narrows the rule: vayehi can signal joy or distress; vayehi bimei signals distress. This is the rule after the objections.
אמר רב אשי: כל ״ויהי״ — איכא הכי ואיכא הכי, ״ויהי בימי״ — אינו אלא לשון צער.
Rav Ashi distinguishes two formulations.
