Unfortunately for students of the bible, the recycling of names can create confusion. There are five rulers named "Herod" mentioned in the New Testament:
1. Herod the Great ruled Palestine at the birth of Christ. He ordered the killing of male babies in Bethlehem and built the Jewish temple in Jerusalem. (Matt. 2:16-18)
2. Herod Archelaus, son of Herod the Great, was the Herod from whom Mary Joseph, and their child withdrew to Galilee to avoid his presence in Judea (Matt. 2:21-23).
3. Herod Antipas ordered the death of John the Baptist (Mark 6:17-28).
4. Herod Agrippa I imprisoned Peter (Acts 12:1-19).
5. Herod Agrippa II was the ruler before whom Paul made his defense. (Acts 25:13)
Without paying close attention, it could accidentally be assumed that one king lived several generations.
