Analysis
According to the theory of Markan Priority this verse is based closely on the very similar . The verse refers to John the Baptist, the central character of Matthew 3. It refers to his arrest by Herod Antipas. The Gospel of Matthew does not go into greater detail about his arrest until chapter 14.

Jesus returns to Galilee where he was raised, but left to be baptized in Matthew 3:13. Schweizer notes that the text does not make clear that the arrest of John the Baptist was the cause of Jesus' return to Galilee, only that the two events occurred at the same time. However, France notes that the word withdrew in Matthew almost always refers to a retreat from hostile forces, implying that is what is happening here. Both Judea and Galilee were under the control of Herod Antipas at this point, so unlike Matthew 2:22 this is not a move to the domain of a different ruler. It is perfectly plausible that distant Galilee would be safer for John's followers than the area around the Jordan.

Matthew also says nothing about what occurred between the temptation and arrest of John. Jones, and most others readers, believe that some months likely elapse. There is no historical record of exactly when John was arrested, which would clarify the dating.

Jesus is often portrayed as serving as one of John's disciples during this period. France agrees with this theory. He thus sees the arrest as causing an important change in Jesus' ministry. In the area by the Jordan it is presumed that Jesus adopted John's baptism based ministry. France argues the flight to Galilee induced a transition to a ministry based on itinerant preaching.

The term translated as "cast into prison," or more accurately "delivered up" is one that will reappear frequently in the reports of Jesus' own imprisonment. Though Nolland notes that Matthew does not contain the same extensive John/Jesus parallels as Mark.

Commentary from the Church Fathers
Rabanus Maurus: Matthew having related the forty days’ fast, the temptation of Christ, and the ministry of Angels, proceeds, Jesus having heard that John was cast into prison.

Pseudo-Chrysostom: By God without doubt, for none can effect anything against a holy man, unless God deliver him up. He withdrew into Galilee, that is, out of Judæa; both that He might reserve His passion to the fit time, and that He might set us an example of flying from danger.

Chrysostom:  It is not blameworthy not to throw one's self into peril, but when one has fallen into it, not to endure manfully. He departed from Judæa both to soften Jewish animosity, and to fulfil a prophecy, seeking moreover to fish for those masters of the world who dwelt in Galilee. Note also how when He would depart to the Gentiles, He received good cause from the Jews; His forerunner was thrown into prison, which compelled Jesus to pass into Galilee of the Gentiles.
