Toledot, Toldos, or Tol'doth (תּוֹלְדֹת — Hebrew for “generations” or “descendants,” the second word and the first distinctive word in the parshah) is the sixth weekly Torah portion (parshah) in the annual Jewish cycle of Torah reading. It constitutes Genesis 25:19–28:9. Jews in the Diaspora read it the sixth Sabbath after Simchat Torah, generally in November or early December.

Isaac was 40 years old when he married Rebekah, and when she proved barren, Isaac pleaded with God on her behalf, and God allowed Rebekah to conceive. (Genesis 25:20–21) As twins struggled in her womb, she inquired of God, who answered her that two separate nations were in her womb, one mightier than the other, and the older would serve the younger. (Genesis 25:22–23) When Rebekah gave birth, the first twin emerged red and hairy, so they named him Esau, and his brother emerged holding Esau’s heel, so they named him Jacob. (Genesis 25:24–26) Isaac was 60 years old when they were born. (Genesis 25:26)

Esau became a skillful hunter and outdoorsman, but Jacob remained a mild man and camp-bound. (Genesis 25:27) Isaac favored Esau for his game, but Rebekah favored Jacob. (Genesis 25:28) Once when Jacob was cooking, Esau returned to the camp famished and demanded some of Jacob’s red stew. (Genesis 25:29–30) Jacob demanded that Esau first sell him his birthright, and Esau did so with an oath, spurning his birthright. (Genesis 25:31–34)
