Core Text of Chazal

Core Text
לַמּוֹעֵד אָשׁוּב אֵלֶיךָ. מִכָּאן דְּבַפֶּסַח נוֹלַד יִצְחָק, שֶׁהֲרֵי בַּפֶּסַח הָיָה עוֹמֵד וְאָמַר לָהּ לַמּוֹעֵד אָשׁוּב אֵלֶיךָ כָּעֵת חַיָּה וּלְשָׂרָה בֵן.

English: “At the appointed time I will return to you.” From here we learn that Yitzchak was born on Pesach, for He was standing [speaking] on Pesach and said to her, “At the appointed time I will return to you, at this season, and Sarah shall have a son.”

On the daf / in context: The phrase “at this season” is taken to mean that the birth would occur exactly one year later on the same calendar date, which the sugya identifies as Pesach.

Type of Learning

Derash on the verse (Bavli sugya) — not a formal named middah of the 13. The timing language fixes the birth date relative to the announcement.

What Is Learned

Yitzchak was born on Pesach; the promise was made on Pesach and the birth occurred “at this season” one year later.
