Bede the Venerable
Catena Aurea · Johannesevangelium 2
And found in the temple those that sold oxen and sheep and doves, and the changers of money sitting: And when he had made a scourge of small cords, he drove them all out of the temple, and the sheep, and the oxen; and poured out the changers’ money, and overthrew the tables; And said unto them that sold doves, Take these things hence; make not my Father’s house an house of merchandise. And his disciples remembered that it was written, The zeal of thine house hath eaten me up.
Those however, who came from a distance, being unable to bring with them the animals required for sacrifice, brought the money instead. For their convenience the Scribes and Pharisees ordered animals to be sold in the temple, in order that, when the people had bought and offered them afterwards, they might sell them again, and thus make great profits. And changers of money sitting; changers of money sat at the table to supply change to buyers and sellers. But our Lord disapproving of any worldly business in His house, especially one of so questionable a kind, drove out all engaged in it.
