Perjury

Okay kiddo, have you ever promised to tell the truth and then lied? That is called lying under oath, and it's called perjury. When you give your word to tell the truth in a court of law, it is very important to be honest. That's because if you lie, you can get into big trouble because perjury is against the law. In fact, people can go to jail if they lie under oath! So always remember, it's important to tell the truth when you promise to.
