But the Jews felt very humiliated to have to do this. When Jesus became an adult, the law still stood. And Jesus could have easily talked about how unfair this law was. He could have told the Jews to no longer carry these burdens for the Romans. But instead, Jesus said something very interesting.
Twain means two.
Jesus was telling them to carry the burden two miles instead of one. By doing this, they would demonstrate their willingness to get along. They would demonstrate their desire to serve all men. The next time you think a rule is not fair, the next time you do not like a rule your parents made, the next time you think you are being treated wrongly, think about Jesus talking about going two miles instead of one. Even adults have a very hard time with this thought.
