Money-changer: (Matthew 21:12; Mark 11:15; John 2:15) Every Israelite from twenty years and
upwards had to pay
(Exodus 30:13-15) into the sacred treasury half a
shekel every year as an offering to Jehovah, and that in the exact
Hebrew half-shekel piece. There was a class of men, who frequented
the temple courts, who exchanged at a certain premium foreign moneys
for these half-shekels to the Jews who came up to Jerusalem from all
parts of the world. When our Lord drove the traffickers out of the
temple, these money-changers fared worst. Their tables were overturned
and they themselves were expelled.
