Albert Barnes on John 8:1

Mount of Olives. The mountain about a mile directly east of Jerusalem. Mt 21:1. This was the place in which he probably often passed the night when attending the feasts at Jerusalem. The Garden of Gethsemane, to which he was accustomed to resort (Jn 18:2), was on the western side of that mountain, and Bethany, the abode of Martha and Mary, on its east side, Jn 11:1.
