Abel

Offered a sacrifice that pleased God, which provoked his brother Cain to kill him out of jealousy (Genesis 4). Despite being a brief figure, Abel echoes through Scripture. Hebrews 11:4 says 'by faith Abel offered a more acceptable sacrifice' and that 'through his faith, though he died, he still speaks.' Jesus referenced Abel's murder as the beginning of a long line of righteous blood shed on earth (Matthew 23:35).
