Barabbas

"I.e., son of Abba or of a father, a notorious robber whom Pilate" "proposed to condemn to death instead of Jesus, whom he wished to" "release, in accordance with the Roman custom (John 18:40; Mark" 15:7; Luke 23:19). But the Jews were so bent on the death of Jesus that they demanded that Barabbas should be pardoned (Matt. 27:16-26; Acts 3:14). This Pilate did.
