Jesus Ministers in Gentile Territory - the Syro-phoenician Woman - the Feeding of Four Thousand Men (7:23-8:26).
Having made His point strongly Jesus now moved to Gentile territory and seemingly remained there until Mark 8:10, where after a brief visit to Galilee He again returned to Decapolis. But first he moved to the borders of Tyre and Sidon. Then from the borders of Tyre He travelled through Sidon down to the Sea of Galilee ‘through the midst of the borders of Decapolis'. All this was Gentile territory. There would seem to have been a specific intention of avoiding Galilee.
Various reasons have been suggested for this. Firstly that He was avoiding Herod's threatening, secondly that He was removing Himself from the attacks of the Rabbis, thirdly that He was seeking privacy, possibly so that He could concentrate on teaching His disciples, and fourthly that He wanted to move on into other regions with His message. The first is never even hinted at and is unlikely as a main reason because Jesus' only reference to Herod's later intentions against Him were answered with quiet defiance (Luke 13:32). At this stage Herod still thought of Him as John the Baptiser returned from the dead and probably wanted to keep well clear of Him. The second is also unlikely as a main reason as nothing is suggested of further intentions to kill Him and He was not afraid of their criticisms. The third, seeking privacy, is one stated reason (Mark 7:24), although there is no specific indication that at that point He was concentrating on teaching His disciples. The fourth is very possible, although interestingly His preaching there is not mentioned but assumed (Mark 8:1). All four factors may have contributed to His decision with the last probably being finally the main factor, especially after the incident with the Syro-phoenician woman.
But we must also bear in mind that it may be Mark himself who is intending to bring this out. That what we have here was rather an impression that Mark was seeking to convey as he illustrates the expansion of Jesus' ministry, that Jesus' words and logic had now opened the way to His ministry in Gentile territory, rather than that He was avoiding Galilee.
