The next day Jesus curses a fig tree for not having any figs on it. Sounds strange. The disciples point out to him that figs are not in season.
They proceed to the temple, where Jesus disrupts the daily activities throwing tables over and chasing out the people who sell animals for sacrifice, as well as the people who sell the commemorative coins that have to be used to purchase the animals.
Their traditional purpose there has been to alleviate the stress on people who had to travel a long way and would otherwise have to cart in an awful lot of odd things like doves and cattle and sheep to perform their daily rituals. This way they could just pay for it.
The Jews held two provinces: Judea and Galilee. The two areas were not contiguous, and Galilee was always at a disadvantage. Jerusalem, the capital where the scriptures said all the big money had to be managed, was in Judea. People from Galilee - like, let's say, Jesus - were at the mercy of their prices. Jesus threw them out of the temple and called them a den of thieves. Good for him I say.
The scribes and the chief priests heard, and decided to kill him.
