Hypocrites are people who profess one thing but live another.
People who claim to be God's people, but who really do not serve God are hypocrites. Such people asked Jesus for the purpose of entangling Him. Rome ruled over Israel, and the Hebrews hated the Romans. The Pharisees knew that Jesus was ethical, and knew that Jesus would agree that the taxes should be paid to Caesar. They also knew the people hated Caesar.
