As all the Israelites celebrated the drowning of thousands and thousands of soldiers, whose corpses were washing up on the shores, Moses and his sister Miriam wrote a hit song. And then things took a turn for the worse. 

Anyone with Google, could see that the journey from the eastern shores of the Red Sea to Israel, would take maybe 200 hours at most, turned into a much longer journey. They would go days without food or water and start mentioning to their leader that they need food and water to survive and he would get angry at them because he wasn't a very good leader.

Luckily, God gave them some mystery food that came with conditions, as everything does with him, and Moses would hit rocks with his stick... which somehow produced water.

This episode ends with Moses' father-in-law, Jethro, coming out and giving Moses advice on having a multi-tiered court system.
