shall live by them
10:5 shall live by them. Paul refers here to Leviticus 18:5. If one could keep the law in its entirety, he would be acceptable to God, but the law must be taken in whole or not at all. Breaking any part of it comes short of God’s standard (Galatians 3:12, Romans 3:23; James 2:10). Only Christ fulfilled it (Matthew 5:17).
