Herodias's role in John the Baptist's murder is similar to the story of Jezebel (1 Kings 19:1–2). Like Jezebel, she pushed for the death of a prophet.
Herod gave in to pressure (Mark 6:26–28). This points ahead to what Pontius Pilate later did. Pilate ordered that Jesus be put to death even though he believed Jesus was innocent (compare 6:20, 25–28 with 15:6–15).
