Now, technically, this happened on Day 1 right after the Triumphal Entry, but I feel like this deserves its own mention.
After coming into Jerusalem, the Lord Jesus goes into the Temple. In the Temple, he finds people about all sorts of business and activity. Much of it is centered on personal profit derived from those who have come to worship the One True God.
This angers Jesus. Something to be aware of as we consider Jesus is this: He's not always huggy-man. Sometimes, when the honor of God is at stake, He is angry. His anger comes out here against those who are blocking people whose hearts are rightly seeking God.
These folks are more concerned for themselves than for righteousness. That's not a good place to be.
The point to be taken here is this: Jesus is headed to the Cross to remove the curse of sin by taking that punishment. He will take the force of the death we deserve—that price is not too high for Him to pay. Neither, though, will He stand by and let people interfere with those seeking God.
