Rabbinic Texts Intro: What is Midrash?

Midrash as Re-imagining the Bible

(כג) וַיִּקַּ֨ח אַבְרָהָ֜ם אֶת־יִשְׁמָעֵ֣אל בְּנ֗וֹ וְאֵ֨ת כָּל־יְלִידֵ֤י בֵיתוֹ֙ וְאֵת֙ כָּל־מִקְנַ֣ת כַּסְפּ֔וֹ כָּל־זָכָ֕ר בְּאַנְשֵׁ֖י בֵּ֣ית אַבְרָהָ֑ם וַיָּ֜מָל אֶת־בְּשַׂ֣ר עָרְלָתָ֗ם בְּעֶ֙צֶם֙ הַיּ֣וֹם הַזֶּ֔ה כַּאֲשֶׁ֛ר דִּבֶּ֥ר אִתּ֖וֹ אֱלֹהִֽים׃ (כד) וְאַ֨בְרָהָ֔ם בֶּן־תִּשְׁעִ֥ים וָתֵ֖שַׁע שָׁנָ֑ה בְּהִמֹּל֖וֹ בְּשַׂ֥ר עָרְלָתֽוֹ׃ (כה) וְיִשְׁמָעֵ֣אל בְּנ֔וֹ בֶּן־שְׁלֹ֥שׁ עֶשְׂרֵ֖ה שָׁנָ֑ה בְּהִ֨מֹּל֔וֹ אֵ֖ת בְּשַׂ֥ר עָרְלָתֽוֹ׃ (כו) בְּעֶ֙צֶם֙ הַיּ֣וֹם הַזֶּ֔ה נִמּ֖וֹל אַבְרָהָ֑ם וְיִשְׁמָעֵ֖אל בְּנֽוֹ׃ (כז) וְכָל־אַנְשֵׁ֤י בֵיתוֹ֙ יְלִ֣יד בָּ֔יִת וּמִקְנַת־כֶּ֖סֶף מֵאֵ֣ת בֶּן־נֵכָ֑ר נִמֹּ֖לוּ אִתּֽוֹ׃ (פ)

Genesis 17:23-27

(23) Then Abraham took his son Ishmael, and all his homeborn slaves and all those he had bought, every male in Abraham’s household, and he circumcised the flesh of their foreskins on that very day, as God had spoken to him. (24) Abraham was ninety-nine years old when he circumcised the flesh of his foreskin, (25) and his son Ishmael was thirteen years old when he was circumcised in the flesh of his foreskin. (26) Thus Abraham and his son Ishmael were circumcised on that very day; (27) and all his household, his homeborn slaves and those that had been bought from outsiders, were circumcised with him.

This is the biblical account.

ספר היובלים ט״ו:כ״ג-כ״ז

(כג) ויכל לדבר אתו ויעל אלהים:

(כד) ויקח אברהם את ישמעאל בנו ואת כל ילידי ביתו ואת מקנת זהבו כל זכר אשר היה בביתו וימול את בשר ערלתם:

(כה) וביום הזה נמול אברהם ואנשי ביתו נמולו וכל מקנת זהבו מאת בני הנכרים נמולו אתו:

(כו) והחוק הזה הוא לכל הדורות עד עולם:

(כז) ואין לשנות את הימים ולא לעבור על יום אחד משמונת הימים כי ברכת עולם היא חרותה וכתובה על לוחות השמים:

Book of Jubilees 15:23-27

(23) And He left off speaking with him, and God went up from Abraham.

(24) And Abraham did according as God had said unto him, and he took Ishmael his son, and all that were born in his house, and whom he had bought with his money, every male in his house, and circumcised the flesh of their foreskin.

(25) And on the selfsame day was Abraham circumcised, and all the men of his house, (and those born in the house), and all those, whom he had bought with money from the children of the stranger, were circumcised with him.

(26) This law is for all the generations for ever,

(27) and there is no circumcision of the days, and no omission of one day out of the eight days; for it is an eternal ordinance, ordained and written on the heavenly tables.
