The date is somewhat difficult to determine with any degree of reliability. The first Passover of Jesus' ministry is believed to have occurred in A. D. 27. His baptism at John's hands took place immediately before that time. John's imprisonment in the tower of Machaerus in all probability began in A. D. 27 and in the first half of that year, but Herod's unwillingness to put him to death may have delayed the climax until the beginning of A. D. 28. Tradition says he was buried in Samaria.
