He made a whip of cords, and threw all out of the temple, both the sheep and the oxen; and he poured out the changers' money, and overthrew their tables.

 Pilgrims arrived from all over the world with all kinds of coins. So in the Temple courts there sat the money-changers. If their trade had been straightforward they would have been fulfilling an honest and a necessary purpose. But what they did was to charge one ma'ah, a coin worth about 1 pence, for every half-shekel they changed, and to charge another ma'ah on every half-shekel of change they had to give if a larger coin was tendered. So, if a man came with a coin the value of which was two shekels, he had to pay 1 pence to get it changed, and other 3 pence to get his change of three half-shekels. In other words the money-changers made 4 pence out of him--and that, remember, was one day's wage.
