But the reason for this command to flee is perplexing. 'Ye shall not have gone over the cities of Israel till the Son of Man be come.' Is Jesus here reverting to the narrower immediate mission of the apostles? What 'coming' is referred to? We have seen that the first mission of the twelve was the theme of verses 5-15, and was there pursued to its ultimate consequences of final judgment on rejecters, whilst the wider horizon of a future mission opens out from verse 16 onwards. A renewed contraction of the horizon is extremely unlikely. It would be as if 'a flower should shut and be a bud again.' The recurrence in verse 23 of 'Verily I say unto you,' which has already occurred in verse 15, closing the first section of the charge, makes it probable that here too a section is completed, and that probability is strengthened if it is observed that the same phrase occurs, for a third time, in the last verse of the chapter, where again the discourse soars to the height of contemplating the final reward. The fact that the apostles met with no persecution on their first mission, puts out of court the explanation of the words that refers them to that mission, and takes the 'coming' to be Jesus' own appearances in the places they had preceded Him as His heralds. The difficult question as to what is the _terminus ad quem_ pointed to here seems best solved by taking the 'coming of the Son of Man' to be His judicial manifestation in the destruction of Jerusalem and the consequent desolation of many of 'the cities of Israel,' whilst at the same time, the nearer and smaller catastrophe is a prophecy and symbol of the remoter and greater 'day of the Son of Man' at the end of the days. The recognition of that aspect of the fall of Jerusalem is forced on us by the eschatological parts of the Gospels, which are a bewildering whirl without it. Here, however, it is the crash of the fall itself which is in view, and the thought conveyed is that there would be cities enough to serve for refuges, and scope enough for evangelistic work, till the end of the Jewish possession of the land.
