You know the Midrashim. Let's try to understand why Hazal told Og's story the way they did. Make sure to have a Chumash available, seeing the textual parallels inside will be very helpful. 

What happened to Chur? He appears out of no where and then we never hear about him again... A closer look at who he was may help us unravel the mystery.

They are Moshe and Aaron's first cousins. They may be behind the scenes, but they may be some of the founding members of a very important group of volunteers. Can you guess what I'm referring to? If not take a few minutes and learn something new. 

We know she is the daughter of Yitro and wife of Moshe, but what do we know about her?
