New Defender's Study Bible Notes
4:4 Abel. Abel was a man of faith, the first listed in the chapter of faith (Hebrews 11). Since he brought a “by faith...a more excellent sacrifice” (Hebrews 11:4), it is evident that God had given instruction concerning the sacrifice, which Abel believed and obeyed. The Lord Jesus described him as “righteous” (Matthew 23:35) and even as one of God’s prophets (Luke 11:50,51).
