John Wesley on Genesis 35:22

When Israel dwelt in that land - As if he were then absent from his family, which might be the unhappy occasion of these disorders. Though perhaps Bilhah was the greater criminal, yet Reuben's crime was so provoking that for it he lost his birth - right and blessing, Ge 49:4. And Israel heard it - No more is said, that is enough; he heard it with the utmost grief and shame, horror and displeasure.
