SEV Biblia, Chapter 4:12
¶ Mas oyendo Jess que Juan estaba preso, se volvi a Galilea;
John Gill's Bible Commentary
Ver. 12. Now, when Jesus had heard that John was cast into prison , etc.] John was cast into prison by Herod; the reason of it may be seen in ( Matthew 14:3,4). The prison into which he was cast, according to Josephus f211 , was the castle of Machaeras: here he continued some time before he was put to death; for from hence he sent two disciples to Jesus, to know if he was the Messiah, ( Matthew 11:2). Now when Jesus heard of this his imprisonment, he departed into Galilee ; not so much on account of safety, or for fear of Herod, but to call his disciples, who lived in that country.
Matthew Henry Commentary
Verses 12-17 - It is just with God to take the gospel and the means of grace, from those that slight them and thrust them away. Christ will not stay lon where he is not welcome. Those who are without Christ, are in the dark They were sitting in this condition, a contented posture; they chose i rather than light; they were willingly ignorant. When the gospel comes light comes; when it comes to any place, when it comes to any soul, i makes day there. Light discovers and directs; so does the gospel. The doctrine of repentance is right gospel doctrine. Not only the auster John Baptist, but the gracious Jesus, preached repentance. There is still the same reason to do so. The kingdom of heaven was not reckone to be fully come, till the pouring out of the Holy Spirit afte Christ's ascension.

Vincent's NT Word Studies
12. Was cast into prison (paredoqh). The verb means, first, to give, or hand over to another. So, to surrender a city or a person, often with the accompanying notion of treachery. The Rev., therefore, rightly renders, was delivered up.
Robertson's NT Word Studies
4:12 {Now when he heard} (akousas de). The reason for Christ's return to Galilee is given here to be that John had been delivered up into prison. The Synoptic Gospels skip from the temptation of Jesus to the Galilean ministry, a whole year. But for #Joh 1:19-3:36 we should know nothing of the "year of obscurity" (Stalker). John supplies items to help fill in the picture. Christ's work in Galilee began after the close of the active ministry of the Baptist who lingered on in prison for a year or more.
