Leviticus 9-11

In 10:10 the LORD spoke to Aaron about the holiness that God expects of his priests. They are to be an example to all the people of holiness. The multitudes of Israel would look to the priest's families to witness the practices of living holy. In 11:45 God's reason for the people to be selective in what they eat was to display holiness to each other and the world. Their discriminating diet was to bear witness to every person whom they encountered that they were different. I don't believe God intended this to be a bragging point, but rather to be an expression of surrender and thanksgiving to the LORD for their liberty. God gave them their freedom when he brought them out of Egypt.
