What does Matthew 14:1 mean?

Over the course of His ministry, Jesus became progressively more famous. This is not surprising. Not only was Jesus performing powerful miracles of healing and casting out demons, He was being followed from place to place by large crowds and beginning to publicly conflict with the religious leaders.

One of the people who heard of Jesus' fame was Herod the tetrarch, also known as Herod Antipas. This is not the same man, Herod the Great, who tried to kill Jesus as a baby after learning of His existence from the wise men (Matthew 2:7, 13). After his death, Herod the Great's kingdom of Israel and surrounding territories was split by the Romans between three of his sons. The person described in this passage is one of those sons. Herod Antipas became the ruler over the part of the kingdom that included Galilee in the north and Perea along the east side of the Jordan River. Most of Jesus' ministry so far has taken place within that territory. Antipas ruled from 4 BC To AD 39 and presided over one of the trials of Jesus (Luke 23:7–12).

Some scholars suggest Herod might have heard about Jesus from a man named Chuza, his household manager. Chuza's wife Joanna is mentioned in Luke 8:1–3 as one of "some women who had been healed of evil spirits and infirmities" who were travelling with and providing for Jesus and the disciples.
