The Galilean ministry was drawing to a close, for the "great Light" which had risen over the northern province must now move southward, to set behind a cross and a grave. Jesus, however, is reluctant to leave these borders, amid whose hills the greater part of His life has been spent, and among whose composite population His greatest successes have been won, without one last effort. Calling together the Twelve, who hitherto have been Apostles in promise and in name rather than in fact, He lays His plans before them. Dividing the district into sections, so as to equalize their labours and prevent any overlapping, He sends them out in pairs; for in the Divine arithmetic two are more than twice one, more than the sum of the separate units by all the added force and strength of fellowship. They are to be the heralds of the new kingdom, to "preach the kingdom of God," their insignia no outward, visible badge, but the investiture of authority over all demons, and power over all diseases. Apostles of the Unseen, servants of the Invisible King, they must dismiss all worldly cares; they must not even make provision for their journey, weighting themselves with such _impedimenta_ as wallets stored with bread or changes of raiment. They must go forth in an absolute trust in God, thus proving themselves citizens of the heavenly kingdom, whose gates they open to all who will repent and step up into them. They may take a staff, for that will help rather than hinder on the steep mountain paths; but since the King's business requireth haste, they must not spend their time in the interminable salutations of the age, nor in going about from house to house; such changes would only distract, diverting to themselves the thought which should be centred upon their mission. Should any city not receive them, they must retire at once, shaking off, as they depart, the very dust from their feet, as a testimony against them.
