Leviticus 11:47 New International Version (NIV)
47 You must distinguish between the unclean and the clean, between living creatures that may be eaten and those that may not be eaten.’”
This restricted diet was to make sure that the Israelites were healthy, so disease would not be transmitted. It also distinguished them from other nations. The pig was a common sacrifice used in pagan religions. Finally, this way of eating kept the Israelites from bad associations. Serpents move around on the ground and this symbolized sin, so the people were to keep from this. God set boundaries for our good. He wants us to be healthy spiritually. Today, we stay healthy by reading God’s Word daily and obeying him.
