God made tunics of skin for Adam and his wife and clothed them after they had eaten from the tree of the knowledge of good and evil. This act followed their own attempt to cover their nakedness by sewing fig leaves together, an effort that arose once their eyes were opened and they viewed their physical differences as a source of division rather than the unity God had intended in creation. By contrast, the tunics required the sacrifice of an animal, providing the first indication of the cost required to restore mankind to God and to reunite what sin had divided. This provision pointed forward to the perfect sacrifice that would ultimately bring all people back under the banner of truth, granting renewed access to the tree of life through Jesus Christ. The tunics therefore stand as the initial picture of self-sacrifice that overcomes the curse of relational conflict introduced in Genesis 3:16, a conflict in which human efforts to determine good and evil produce only further separation. They illustrate that lasting unity cannot come from coverings fashioned by human wisdom but only from the covering supplied by God Himself, which enables His people to walk in the fear of the Lord and to live under His banner in every circumstance.
