בָּרוּךְ אַתָּה ה' אֱלהֵינוּ מֶלֶךְ הָעולָם אֲשֶׁר קִדְּשָׁנוּ בְּמִצְותָיו וְצִוָּנוּ לַעֲסוק בְּדִבְרֵי תורָה:

Blessed are You, Lord, our God, King of the Universe, Who has sanctified us with his commandments and commanded us to be involved with words of Torah.

Rachel
(יג) וַיַּ֥עַל מֵעָלָ֖יו אֱלֹהִ֑ים בַּמָּק֖וֹם אֲשֶׁר־דִּבֶּ֥ר אִתּֽוֹ׃ (יד) וַיַּצֵּ֨ב יַעֲקֹ֜ב מַצֵּבָ֗ה בַּמָּק֛וֹם אֲשֶׁר־דִּבֶּ֥ר אִתּ֖וֹ מַצֶּ֣בֶת אָ֑בֶן וַיַּסֵּ֤ךְ עָלֶ֙יהָ֙ נֶ֔סֶךְ וַיִּצֹ֥ק עָלֶ֖יהָ שָֽׁמֶן׃ (טו) וַיִּקְרָ֨א יַעֲקֹ֜ב אֶת־שֵׁ֣ם הַמָּק֗וֹם אֲשֶׁר֩ דִּבֶּ֨ר אִתּ֥וֹ שָׁ֛ם אֱלֹהִ֖ים בֵּֽית־אֵֽל׃ (טז) וַיִּסְעוּ֙ מִבֵּ֣ית אֵ֔ל וַֽיְהִי־ע֥וֹד כִּבְרַת־הָאָ֖רֶץ לָב֣וֹא אֶפְרָ֑תָה וַתֵּ֥לֶד רָחֵ֖ל וַתְּקַ֥שׁ בְּלִדְתָּֽהּ׃ (יז) וַיְהִ֥י בְהַקְשֹׁתָ֖הּ בְּלִדְתָּ֑הּ וַתֹּ֨אמֶר לָ֤הּ הַמְיַלֶּ֙דֶת֙ אַל־תִּ֣ירְאִ֔י כִּֽי־גַם־זֶ֥ה לָ֖ךְ בֵּֽן׃ (יח) וַיְהִ֞י בְּצֵ֤את נַפְשָׁהּ֙ כִּ֣י מֵ֔תָה וַתִּקְרָ֥א שְׁמ֖וֹ בֶּן־אוֹנִ֑י וְאָבִ֖יו קָֽרָא־ל֥וֹ בִנְיָמִֽין׃ (יט) וַתָּ֖מׇת רָחֵ֑ל וַתִּקָּבֵר֙ בְּדֶ֣רֶךְ אֶפְרָ֔תָה הִ֖וא בֵּ֥ית לָֽחֶם׃ (כ) וַיַּצֵּ֧ב יַעֲקֹ֛ב מַצֵּבָ֖ה עַל־קְבֻרָתָ֑הּ הִ֛וא מַצֶּ֥בֶת קְבֻֽרַת־רָחֵ֖ל עַד־הַיּֽוֹם׃ (כא) וַיִּסַּ֖ע יִשְׂרָאֵ֑ל וַיֵּ֣ט אׇֽהֳלֹ֔ה מֵהָ֖לְאָה לְמִגְדַּל־עֵֽדֶר׃

(13) God parted from him at the spot where He had spoken to him; (14) and Jacob set up a pillar at the site where He had spoken to him, a pillar of stone, and he offered a libation on it and poured oil upon it. (15) Jacob gave the site, where God had spoken to him, the name of Bethel. (16) They set out from Bethel; but when they were still some distance short of Ephrath, Rachel was in childbirth, and she had hard labor. (17) When her labor was at its hardest, the midwife said to her, “Have no fear, for it is another boy for you.” (18) But as she breathed her last—for she was dying—she named him Ben-oni; but his father called him Benjamin. (19) Thus Rachel died. She was buried on the road to Ephrath—now Bethlehem. (20) Over her grave Jacob set up a pillar; it is the pillar at Rachel’s grave to this day. (21) Israel journeyed on, and pitched his tent beyond Migdal-eder.

מצבה על קבורתה מפני שהקבר על אם הדרך ויש לחוש לחטוטי קברי:
מצבה על קבורתה, this was for protection against the grave being damaged or exhumed by people doing this for nefarious purposes, as it was located at the crossroads where there is a lot of traffic. [I presume it could not be in a field as Yaakov would not violate private property to bury his dead. Ed.]
Isaac
(כז) וַיָּבֹ֤א יַעֲקֹב֙ אֶל־יִצְחָ֣ק אָבִ֔יו מַמְרֵ֖א קִרְיַ֣ת הָֽאַרְבַּ֑ע הִ֣וא חֶבְר֔וֹן אֲשֶׁר־גָּֽר־שָׁ֥ם אַבְרָהָ֖ם וְיִצְחָֽק׃ (כח) וַיִּֽהְי֖וּ יְמֵ֣י יִצְחָ֑ק מְאַ֥ת שָׁנָ֖ה וּשְׁמֹנִ֥ים שָׁנָֽה׃ (כט) וַיִּגְוַ֨ע יִצְחָ֤ק וַיָּ֙מׇת֙ וַיֵּאָ֣סֶף אֶל־עַמָּ֔יו זָקֵ֖ן וּשְׂבַ֣ע יָמִ֑ים וַיִּקְבְּר֣וּ אֹת֔וֹ עֵשָׂ֥ו וְיַעֲקֹ֖ב בָּנָֽיו׃ {פ}
(27) And Jacob came to his father Isaac at Mamre, at Kiriath-arba—now Hebron—where Abraham and Isaac had sojourned. (28) Isaac was a hundred and eighty years old (29) when he breathed his last and died. He was gathered to his kin in ripe old age; and he was buried by his sons Esau and Jacob.
אשר גר שם אברהם ויצחק, אמר לפי שיעקב גם כן גר שם להודיע כי ראוי לאדם לגור בעיר אבותיו לכבוד האבות שהם נקברים שם, וכן אמר העיר קברת אבותי (נחמיה ב' ה') תלה הדבר בקברת אבותיו:
אשר גר שם אברהם ויצחק, this is mentioned seeing that now Yaakov also sojourned there. It teaches that it is appropriate for a person to be buried in the town where his ancestors had lived as it is a sign of honour for his ancestors who were also buried there. Nechemyah speaks repeatedly of “the city where my fathers have been buried;” he attributed the significance to the fact that several generations of his ancestors had been buried in the same place. (Nechemyah 2,3 and 2,5)
שֶׁכְּפוּלָה בְּזוּגוֹת. ״מַמְרֵא קִרְיַת אַרְבַּע״, אָמַר רַבִּי יִצְחָק, קִרְיַת הָאַרְבַּע זוּגוֹת: אָדָם וְחַוָּה, אַבְרָהָם וְשָׂרָה, יִצְחָק וְרִבְקָה, יַעֲקֹב וְלֵאָה.
Rather, it is called Machpelah in the sense that it is doubled with the Patriarchs and Matriarchs, who are buried there in pairs. This is similar to the homiletic interpretation of the alternative name for Hebron mentioned in the Torah: “Mamre of Kiryat Ha’Arba, which is Hebron” (Genesis 35:27). Rabbi Yitzḥak said: The city is called Kiryat Ha’Arba, the city of four, because it is the city of the four couples buried there: Adam and Eve, Abraham and Sarah, Isaac and Rebecca, and Jacob and Leah.
