Moses is one of the most important figures of the Old Testament. He was born when the people of Israel were slaves in Egypt, but he ended up being raised in the house of the Pharaoh. God chose him to be the person to lead the Israelites out of slavery and into freedom in a land of their own. Moses also was the man God selected to receive the law and give it to Israel. The laws are recorded in the first five books of the Old Testament, but the parts of the law that most of us are familiar with are the Ten Commandments. Aaron was a brother of Moses, and he became one of the first priests of Israel. Because Moses was not a very good speaker, Aaron often spoke for him, using the words given to Moses by God.
