Matthew 21:12

And cast out all. Since the Jews came to the temple from all parts of Judea, such as came from a distance did not bring with them their sacrifices, but purchased them at Jerusalem. The money-changers were persons who lent out money to the poor, that they might purchase the victims, &c. But as the law forbade usury, they received other fruits, grapes, &c. in return. These persons, beyond a doubt, beheld a more than human brightness darting from his eyes, otherwise they would not have suffered him to act thus. In the same manner, the servants of the high priest fell down when they came to apprehend Jesus, at these words, I am he. (Nicholas de Lyra.) --- Into the temple. Into that part of it called the court of the Gentiles, where pigeons were to be sold for sacrifices, where there where tables of money-changers, &c. St. Jerome here admires this as one of the greatest of Christ's miracles, that a poor man should be permitted to cast the buyers and sellers out of the temple, to overturn their stalls, their money-tables, &c. without any opposition.
