This must be an authoritative link because of the way they spell Rebekah.

The Rabbis disagree as to the age of Rebekah at the time of her marriage to Isaac. The statement of the Seder 'Olam Rabbah (i.) and Gen. R. (lvii. 1) that Abraham was informed of Rebekah's birth when he ascended Mount Moriah for the 'Aḳedah, is interpreted by some as meaning that Rebekah was born at that time, and that consequently she was only three years old at the time of her marriage...

Some time later, Abraham was told, "Milcah too has borne children to your brother Nahor: (Gen 22:20 TNK)

Other rabbis, however, conclude from calculations that she was fourteen years old, and that therefore she was born eleven years before the 'Aḳedah, both numbers being found in different manuscripts of the Seder 'Olam Rabbah (comp. Tos. to Yeb. 61b). The "Sefer ha-Yashar" (section "Ḥayye Sarah," p. 38a, Leghorn, 1870) gives Rebekah's age at her marriage as ten years.

Rashi going with three carries a lot of weight with Haredi.

according to the Bible:

Isaac brought her into the tent of his mother Sarah, and he married Rebekah. So she became his wife, and he loved her; and Isaac was comforted after his mother's death.

but it was originally

Abraham brought her into the tent of his wife Sarah, and he married Rebekah. So she became his wife, and he loved her; and Abraham was comforted after his wife's death.

[Krupin]

Isaac was stabbed to death on the present. But he managed to make his son Esau. Rebekah had poisoned her husband. Her son, Jacob received the blessing of Abraham. Esau realized that his grandfather had died not a natural death. Rebekah and her son fled to Mesopotamia. On the way to the Euphrates she died. Isaac buried his mother under the oak of weeping. Esau later became Israel.

[Krupin]

From Jacob and Rachel took the tribe Ephraim, Manasseh, Benjamin. From Esau - Israel and Leah took the other tribes.

[Krupin]

This version was not the original. It was intermediate. Initially, Isaac-Jacob was the son of Abraham and Sarah. Israel was the son of Abraham and Hagar. Evil children of Israel had sold Joseph into slavery. They are punished. Joseph made them slaves.
Jerusalem priests edited text. Jacob became the son of crime Rebekah. Israel has become the noble grandson of Sarah. (because Judas - the son of Israel).

[Krupin]

The descendants of Israel were released under an amnesty ( wicked Pharaoh destroyed them - excess penalties). The descendants of Jacob helped win their land. At the end Yahweh and Asherah (they named elohim) was handed to Moses and Joshua tablets (for Israel and Jacob)

That's an interesting statement if somewhat outrageous, do you have any references?

Regarding the context:

Isaac had just come back from the vicinity of Beer-lahai-roi, for he was settled in the region of the Negeb. (Gen 24:62 TNK)

The Rabbis claim he was on the temple mount but Beer-Lahai-Roi is thought to be way south of that.

And Isaac went out walking in the field toward evening and, looking up, he saw camels approaching. (Gen 24:63 TNK)

This used to be translated -

And Isaac went out to meditate in the field at the eventide; and he lifted up his eyes, and saw, and, behold, there were camels coming. (Gen 24:63 JPS)

meditate versus walking, the idea was that Isaac was davening Mincha for the first time

The Talmud states that Mincha was originated by Isaac, and described in Genesis 24:63 by the words "Isaac went out to converse in the field." where the verb "converse" (שוח suwach) refers to with God.[1]

Raising her eyes, Rebekah saw Isaac. She alighted from the camel (Gen 24:64 TNK)

and said to the servant, "Who is that man walking in the field toward us?" And the servant said, "That is my master." So she took her veil and covered herself. (Gen 24:65 TNK)

The servant told Isaac all the things that he had done. (Gen 24:66 TNK)

Isaac then brought her into the tent of his mother Sarah, and he took Rebekah as his wife. Isaac loved her, and thus found comfort after his mother's death.
(Gen 24:67 TNK)

I agree that this is strange... the next verse goes -

Abraham took another wife, whose name was Keturah. (Gen 25:1 TNK)

It's interesting how the themes of camels and tents are so important in the stories where women play a role.

My research (https://www.proza.ru/avtor/krupinsj) . Unfortunately all this translate into English, I can not.

Jerusalem's priests did not compose his book. They (allegedly) corrected a alien book. It was not profitable. These corrections were made in small quantities for a long time. No one suspected that the changes are beneficial to the priests.
The changes were justified by correcting mistakes made earlier (allegedly) in the rewriting of the text or with oral transmission or (allegedly) ancient papyrus rotten and part of the text impossible to read.
This method of editing left clear imprints. As it reconstructed the evolution of the text.
