Catena Aurea on John 2:14–17: Bede

Or, the sheep are works of purity and piety, and they sell the sheep, who do works of piety to gain the praise of men. They exchange money in the temple, who, in the Church, openly devote themselves to secular business. And besides those who seek for money, or praise, or honour from Holy Orders, those too make the Lord’s house a house of merchandize, who do not employ the rank, or spiritual grace, which they have received in the Church at the Lord’s hands, with singleness of mind, but with an eye to human recompense.
