Okay kiddo, so a long time ago there was a very wise man named Rabbi Ishmael. He taught many important things about the holy Jewish scriptures called the Torah.
One of the things that Rabbi Ishmael taught was written down in a special book called a "baraita." This book had all of his teachings, sayings, and explanations about the Torah.
Now, the baraita of Rabbi Ishmael is very important because it helps us understand the Torah better. It tells us things about the Torah that we might not have known before.
For example, Rabbi Ishmael taught that there are 13 different ways that the Torah can be interpreted. Each way is like a different lens that helps us see the Torah in a new and unique way.
So, when we study the baraita of Rabbi Ishmael, we are learning from a very wise man who had a lot of important insights into the Torah. And that helps us become wiser and better people ourselves.
