21 Then Israel journeyed and pitched his tent beyond the tower of Eder.
22 And it happened, when Israel dwelt in that land, that Reuben went and lay with Bilhah his father's concubine; and Israel heard about it.Now the sons of Jacob were twelve: 23 the sons of Leah were Reuben, Jacob's firstborn, and Simeon, Levi, Judah, Issachar, and Zebulun; 24 the sons of Rachel were Joseph and Benjamin; 25 the sons of Bilhah, Rachel's maidservant, were Dan and Naphtali; 26 and the sons of Zilpah, Leah's maidservant, were Gad and Asher. These were the sons of Jacob who were born to him in Padan Aram.
27 Then Jacob came to his father Isaac at Mamre, or Kirjath Arba (that is, Hebron), where Abraham and Isaac had dwelt. 28 Now the days of Isaac were one hundred and eighty years. 29 So Isaac breathed his last and died, and was gathered to his people, being old and full of days. And his sons Esau and Jacob buried him.

Commentary on Genesis 35:21-29
(Read Genesis 35:21-29)
What a sore affliction Reuben's sin was, is shown, " and Israel heard it." No more is said, but that is enough. Reuben thought that his father would never hear of it; but those that promise themselves secrecy in sin, are generally disappointed. The age and death of Isaac are recorded, though he died not till after Joseph was sold into Egypt. Isaac lived about forty years after he had made his will, Genesis 27:2. We shall not die an hour the sooner, but much the better, for timely setting our hearts and houses in order. Particular notice is taken of the agreement of Esau and Jacob at their father's funeral, to show how God had wonderfully changed Esau's mind. It is awful to behold relations, sometimes for a little of this world's goods, disputing over the graves of their friends, while they are near going to the grave themselves.
