This is another "sandwich" or chiastic section in design (cf. Luke 8:40-56). This structural device usually gives unity to the whole section and focuses attention on the central part of it. First, Jesus sent the Twelve on an evangelistic mission throughout Galilee. Luke filled in the period of their mission proper with information about how Herod Antipas and the people perceived Jesus. Third, the writer recorded the return of the Twelve to their Master. The whole mission prefigured the later mission of these and other disciples to the ends of the earth that Acts records. The lessons that Jesus taught about dependence on God and rejection by men apply to the church"s mission in the present dispensation. Jesus" instructions to His missionaries, rather than the activities of the missionaries, are the core of this pericope. However the reader must carefully distinguish the basic principles that Jesus taught from the specific directions that He meant for this particular mission and no other. [source][source][source]
