Mark 15:21

Overview - Mark 15
Jesus brought bound, and accused before Pilate.
Upon the clamour of the common people, the murderer Barabbas is loosed, and Jesus delivered up to be crucified.
16 He is crowned with thorns, spit on, and mocked;
21 faints in bearing his cross;
27 hangs between two thieves;
29 suffers the triumphing reproaches of the Jews;
39 but is confessed by the centurion to be the Son of God;
42 and is honourably buried by Joseph.
