“וישב ראובן AND REUBEN RETURNED — When he (Joseph) was sold he had not been present, for it was his day (his turn) to go to attend to his father (Genesis Rabbah 84:19). Another explanation is: he had not sat with them at the meal because he was occupied with his sack-cloth and fast in penitence for having disturbed his father’s couch (Genesis Rabbah 84:19).”

The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
