Okay buddy, so let's talk about the Levites. They were a special group of people who lived a long time ago in the Bible days. They were part of a big group called the Israelites, and they had a very important job. They were responsible for helping take care of the sacred things in the temple and making sure everything was done the right way during worship.
Now, the Levites didn't have their own land like the other Israelites. Instead, they were given special cities to live in all over the place. They also didn't have to do regular jobs like farming or trading – their job was to serve in the temple and take care of the holy things.
The Levites were set apart from other Israelites because they were the descendants of Levi, one of the 12 sons of Jacob in the Bible. Levi's family was chosen to serve God in a special way, and that's why all of his descendants became Levites.
So, in short, the Levites were a special group of people in the Bible who had an important job of serving in the temple and taking care of the sacred things. They were set apart from other Israelites because they were the descendants of Levi, and they had their own special cities to live in. Pretty cool, right?
