Catena Aurea · Lukasevangelium 19
And he went into the temple, and began to cast out them that sold therein, and them that bought; Saying unto them, It is written, My house is the house of prayer: but ye have made it a den of thieves. And he taught daily in the temple. But the Chief Priests and the Scribes and the chief of the people sought to destroy him, And could not find what they might do: for all the people were very attentive to hear him.
Therefore our Lord teaches generally that all worldly bargains should be far removed from the temple of God; but spiritually He drove away the money-changers, who seek gain from the Lord’s money, that is, the divine Scripture, lest they should discern good and evil.
