Since God instituted circumcision as the sign of the covenant He made with Abraham (Genesis 17:10-11), it predates the Old Covenant by several hundred years. When God called Israel out of Egypt and gave them His laws, He included the command to circumcise male babies (Leviticus 12:3). Circumcision identified the Israelites as physical descendants of Abraham, gave them a sense of national identity, and set them apart from other nations of the world.
