 Gods ceremony house was in Jerusalem, and people had to kill animals there and burn them to show respect to God, and they had to pay tax money to the men that look after Gods house. Jesus went into the yard of Gods ceremony house, and he found men there selling cows, and bulls, and sheep, and pigeons. And there were men that changed the money of other countries into Jewish money so that people could pay that tax. You see, those men that sold things, and changed money, they did that to get some money for themselves.
