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. (See PASSOVER.)
When our Lord drove the traffickers out of the temple, these money-changers fared worst. Their tables were overturned and they themselves were expelled.
