Genesis 25:19–28:9
Isaac and Rebecca endure twenty childless years, until their prayers are answered and Rebecca conceives. She experiences a difficult pregnancy as the "children struggle inside her"; G‑d tells her that "there are two nations in your womb," and that the younger will prevail over the elder.
Esau emerges first; Jacob is born clutching Esau's heel. Esau grows up to be "a cunning hunter, a man of the field"; Jacob is "a wholesome man," a dweller in the tents of learning. Isaac favors Esau; Rebecca loves Jacob. Returning exhausted and hungry from the hunt one day, Esau sells his birthright (his rights as the firstborn) to Jacob for a pot of red lentil stew.
In Gerar, in the land of the Philistines, Isaac presents Rebecca as his sister, out of fear that he will be killed by someone coveting her beauty. He farms the land, reopens the wells dug by his father Abraham, and digs a series of his own wells: over the first two there is strife with the Philistines, but the waters of the third well are enjoyed in tranquility.
Esau marries two Hittite women. Isaac grows old and blind, and expresses his desire to bless Esau before he dies. While Esau goes off to hunt for his father's favorite food, Rebecca dresses Jacob in Esau's clothes, covers his arms and neck with goatskins to simulate the feel of his hairier brother, prepares a similar dish, and sends Jacob to his father. Jacob receives his father's blessings for "the dew of the heaven and the fat of the land" and mastery over his brother. When Esau returns and the deception is revealed, all Isaac can do for his weeping son is to predict that he will live by his sword, and that when Jacob falters, the younger brother will forfeit his supremacy over the elder.
Jacob leaves home for Charan to flee Esau's wrath and to find a wife in the family of his mother's brother, Laban. Esau marries a third wife—Machalath, the daughter of Ishmael.
Malachi 1:1-2:7.
This week's haftorah opens with a mention of the tremendous love G‑d harbors for the children of Jacob, and the retribution He will visit upon the children of Esau who persecuted their cousins. This follows the theme of this week's Torah reading, whose two protagonists are Jacob and Esau.
The prophet Malachi then rebukes the kohanim (priests) who offer blemished and emaciated animals on G‑d's altar: "Were you to offer it to your governor, would he be pleased or would he favor you? . . . O that there were even one among you that would close the doors [of the Temple] and that you would not kindle fire on My altar in vain!"
The haftorah ends with a strong enjoinder to the kohanim to return to the original covenant that G‑d had made with their ancestor, Aaron the High Priest. "True teaching was in his mouth, and injustice was not found on his lips. In peace and equity he went with Me, and he brought back many from iniquity."
. . . Isaac the son of Abraham; Abraham fathered Isaac (25:19)
The cynics of that generation were saying that Sarah had become pregnant from Avimelech, since she had failed to conceive in all the years she was with Abraham. What did G‑d do? He formed the countenance of Isaac to resemble that of Abraham, so that all might attest that Abraham had fathered Isaac. This is the meaning of the repetitious wording of the verse: "Isaac (is certainly) the son of Abraham, (since there is proof that) Abraham fathered Isaac."
(Rashi)
There are children who are embarrassed of their parents, and there are parents who are embarrassed by their children. With Abraham and Isaac it wasn't like that: Isaac prided himself in that he was "Isaac the son of Abraham," and Abraham prided himself in that "Abraham fathered Isaac."
(Midrash Tanchuma; Midrash HaGadol)
