Imagine you have a big book with lots of stories in it, just like your bedtime storybook. In this big book, there are stories that are very important to a special group of people called Jews. They call this big book the Torah.
Now, the Torah is so big and has so many stories that it would take a really long time to read it all at once. So instead, they break it up into smaller parts and read one part each week. This is called the weekly Torah portion.
Each week, Jews all over the world read the same part of the Torah, so they are all learning and thinking about the same story at the same time. They listen to someone called a rabbi read from the Torah and sometimes they talk about what they learned with their friends and family.
The stories in the Torah are really important to Jews because they believe they teach them how to live a good and moral life. So they take the weekly Torah portion very seriously and try to learn as much as they can from it.
