And he spake a parable unto them to this end, that men ought always to pray, and not to faint. The formnla ἕλεγε δὲ καί, literally, "and he spake also," calls attention to the fact that the parable-teaching immediately to follow was a continuation of what had preceded.
Indeed, the connection between the first of the two parables, which urges restless continued prayer, and the picture which the Lord had just drawn of men's state of utter forgetfulness of God, is obvious.
"The Son of man has been rejected; he has gone from view; the masses are plunged in gross worldliness; men of God are become as rare as, in the days of Abraham, they were in Sodom. What, then, is the position of the Church?
That of a widow whose only weapon is incessant prayer. It is only by means of this intense concentration that faith will be preserved. But such is precisely the disposition which Jesus fears may not be found even in the Church at his return" (Godet).
