Jotham was a person in the Bible. He was the son of a king called Uzziah. When his dad got sick, Jotham took over as the king of his country.
Now, being a king was a big job. Jotham had to make sure that everyone in his country was safe and happy. He had to make rules, like a parent sets rules for their child. He also had to make sure people followed those rules.
Jotham did a pretty good job as a king. He made some good rules that helped his people, and he didn't try to do too much or too little.
But one thing that people remember about Jotham is that he was very religious. He believed in God very much, and he worked hard to follow God's rules. Even though he was a king, he knew that he wasn't more important than God.
Jotham is a good example of how someone can be a good leader, but also be humble and faithful to their beliefs.
