John the Baptist, the forerunner of Jesus, baptized Him in the Jordan River, heralding His ministry with a message of repentance and preparation for the Kingdom of God, and was later executed by Herod Antipas.
Herod Antipas, the tetrarch of Galilee and Perea, is notorious for ordering the beheading of John the Baptist at the behest of Herodias’s daughter, Salome, and played a part in the trial of Jesus before being exiled to Gaul.
