Midras Kejadian 26:22: Midrash Tanchuma Buber, Aggadat Bereshit & Bereshit Rabbah

Thus has R. Tanhuma interpreted (Gen. 27:1): NOW IT CAME TO PASS, THAT WHEN ISAAC WAS OLD < AND HIS EYES WERE TOO WEAK TO SEE >. You find that there are twenty generations from Adam to Abraham, and there is no < mention of > old age written about < any of > them except Abraham, as stated (in Gen. 24:1): NOW ABRAHAM WAS OLD.²⁶For parallel accounts, see above, 5:4. Isaac arose, < and > it is also written (in Gen. 27:1): NOW IT CAME TO PASS, THAT WHEN ISAAC WAS OLD. Jacob arose, < and > it is also written (in Gen. 48:10): NOW ISRAEL'S EYES WERE DIM WITH AGE. This text is related (to Ps. 90:16): LET YOUR WORK BE WORTHY FOR YOUR SERVANTS AND YOUR GLORY ON BEHALF OF THEIR CHILDREN. Now GLORY can only be old age and gray hair, as stated (in Prov. 20:29): THE BEAUTY OF THE YOUNG IS THEIR STRENGTH; BUT THE GLORY OF THE OLD IS GRAY HAIR. Ergo (in Ps. 90:16): AND YOUR GLORY ON BEHALF OF THEIR CHILDREN. < These words mean > that Abraham endowed Isaac with five things. Thus have our masters taught (in 'Eduy. 2:9): A FATHER ENDOWS HIS SON WITH FIVE THINGS: WITH BEAUTY, WITH STRENGTH, WITH WEALTH, WITH WISDOM, AND WITH < LENGTH OF > YEARS. How is it shown about BEAUTY? In that Isaac was as handsome as Joseph. It is written of Joseph (in Gen. 39:6): NOW JOSEPH WAS WELL BUILT. Also, when he went to his brothers, they said (in Gen. 37:19): HERE COMES THIS (hallazeh) DREAMER. It is also said of Isaac (in Gen. 24:65): WHO IS THIS (hallazeh) MAN < WALKING IN THE FIELD TO MEET US >? Thus Isaac was as handsome as Joseph. How is it shown that Isaac was mighty in STRENGTH? Look at how many wells he dug! Thus it is stated (in Gen. 26:18-22): THEN ISAAC REDUG < THE WELLS OF WATER >…. AND ISAAC'S SERVANTS DUG…. AND THEY DUG ANOTHER WELL…. THEN HE MOVED FROM THERE AND DUG < ANOTHER WELL >…. Look at the power which he had! Where is it shown about WEALTH? Where it is stated (in Gen. 26:13): AND THE MAN GREW < RICHER AND RICHER >…. It also says (in vs. 14): AND HE POSSESSED FLOCKS < AND HERDS >…. Where is it shown about WISDOM? Where he said to his father (in Gen. 22:7 at the time of his being bound): HERE ARE THE FIRE AND THE WOOD…. [How is it shown] about < LENGTH OF > YEARS? In that he was one hundred and eighty years old < when he died >, while Abraham was < only > one hundred and seventy-five. On account of these five things {through which he had attained merit}, five years more than his father's were added to him. It is therefore stated (in Ps. 90:16): LET YOUR WORK BE WORTHY FOR YOUR SERVANTS…. Anyone who has merit is meritorious in these five things, and anyone who does not have merit is not meritorious and receives five retributions that correspond to them.²⁷See yQid. 1:7 (61a). And who is this anyone? This is Joab, of whom it is stated (in II Sam. 3:29): MAY IT (Abner's blood) FALL UPON THE HEAD OF JOB AND HIS SON;²⁸Masoretic Text: ALL HIS FATHER’S HOUSE. [MAY THE HOUSE OF JOAB NEVER LACK ONE WITH A DISCHARGE, A LEPER, A MALE WHO HANDLES THE SPINDLE, ONE WHO FALLS BY THE SWORD, AND ONE LACKING BREAD]. ONE WITH A DISCHARGE corresponds to STRENGTH. In the case of one who has a discharge, there is no one weaker than he. A LEPER corresponds to BEAUTY. In the case of one who is a leper, even a young < leper >, there is no one more ugly than he. A MALE WHO HANDLES THE SPINDLE corresponds to WEALTH; for he [is one] {like a poor woman is one} who, if not spinning flax, has nothing of which to eat. ONE LACKING BREAD corresponds to WISDOM, as stated (in Prov. 9:5, where Wisdom says): COME AND EAT OF MY BREAD. And ONE WHO FALLS BY THE SWORD corresponds to < LENGTH OF > YEARS. The one who sins is afflicted by them, but the one who is meritorious receives, as did Isaac. David also gave praise (in Ps. 45:17 [16]): INSTEAD OF YOUR PARENTS THERE WILL BE YOUR CHILDREN.

[2] And so all the righteous suffered in their youth and ultimately found comfort. Abraham suffered greatly in his youth, was thrown into a fiery furnace, and was cast out of his father's house. Sixteen kings came against him, and his wife was taken from him by both Pharaoh and Abimelech. He was tested with his only son, Isaac, but in the end found peace, as it says "And Abraham was old, well advanced in age; and the Lord had blessed Abraham in all things" (Genesis 24:1). Isaac also suffered greatly in his youth, as Ishmael took an arrow and tried to kill him. It says, "And Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, playing with her son Isaac" (Genesis 21:9). "Playing" means he took an arrow and tried to kill him. Furthermore, his father Abraham was going to slaughter him, and then famine came, as it says, "Now there was a famine in the land" (Genesis 26:1). Isaac went to Abimelech and became the target of jealousy, as it says, "And the Philistines envied him" (Genesis 26:14). They told him to leave, and he went and settled in Gerar, where he disputed with the shepherds. But ultimately he found comfort, as it says, "Therefore he called it Rehoboth, for he said, 'For now the Lord has made room for us, and we shall be fruitful in the land'" (Genesis 26:22). Similarly, Jacob suffered greatly, as Esau pursued him, and he was enslaved by his sons. He was pursued by Laban and punished through his daughter. His son was sold, and in the end he found peace, as it says, "And Jacob lived in the land of Egypt seventeen years" (Genesis 47:28). Joseph was deeply pained when his brothers despised him, threw him into a pit, sold him into slavery, and he was imprisoned. As it is written, "They afflicted his feet with shackles; iron pierced his soul until his word came to pass and God's word proved him true" (Psalms 105:18-19). Joseph remained silent, as it is written, "He sits alone in silence" (Lamentations 3:28). In the end, he was redeemed, as it is written, "He will not abandon forever, for He desires to show kindness" (Lamentations 3:31). And it is written at the end, "Hurry and go up to my father" (Genesis 45:9).

“Isaac again dug the wells of water that they had dug in the days of Abraham his father, but the Philistines had sealed them after the death of Abraham. He called them names like the names that his father called them” (Genesis 26:18).
“Isaac again dug…” – how many wells did our patriarch Isaac dig in Beersheba? Rabbi Yehuda said: Four. Corresponding to that, his descendants were arrayed into four banners in the wilderness.²²The tribes of Israel were divided into four camps, or banners, in the wilderness (Numbers 2:1–32). The Rabbis say: Five, corresponding to the five books of the Torah.
“The herdsmen of Gerar quarreled with Isaac’s herdsmen, saying: The water is ours. He called the name of the well Esek, because they involved themselves with him” (Genesis 26:20).
“He called the name of the well Esek [because they involved themselves [hitaseku] with him]” – corresponding to the book of Genesis, in which the Holy One blessed be He became involved and created the world.
“Isaac's servants dug in the valley, and they found there a well of fresh water” (Genesis 26:19).
“They dug another well, and they quarreled over it as well. He called it Sitna” (Genesis 26:21).
“He called it Sitna”²³Enmity. – corresponding to the book of Exodus, after, “they embittered their lives with hard work” (Exodus 1:14).
“They found there a well of fresh water” – corresponding to the book of Leviticus, which is filled with many halakhot.
“He called it Shiva; therefore, the name of the city is Beersheba to this day” (Genesis 26:33).
“He called it Shiva” – corresponding to the book of Numbers,²⁴The book of Numbers is divided into three books, which is why there are seven books. which completes the seven [shiva] books of the Torah. But are they not five? Ben Kappara made Numbers into three books: From: “And He spoke” (Numbers 1:1) until: “It was when the Ark traveled” (Numbers 10:35) – a book in and of itself; from “it was when the Ark traveled” and the verse after it – a book in and of itself; and from the end of that passage until the end of the book – a book in and of itself.
“He moved from there and dug another well and they did not quarrel over it. He called its name Reḥovot and he said: As now the Lord has expanded [hirḥiv] for us, and we will be fruitful in the land” (Genesis 26:22).
“He called its name Reḥovot” – corresponding to the book of Deuteronomy, due to, “when the Lord your God will expand [yarḥiv]” (Deuteronomy 12:20) – “as now the Lord has expanded [hirḥiv] for us and we shall be fruitful in the land.”
