John 16:31

And still further admonishing them of their age as still small and infirm in regard to the inner man, "Jesus answered them: Do ye now believe? Behold the hour cometh, yea, is now come, that ye shall be scattered every man to his own, and shall leave me alone. And yet I am not alone, because the Father is with me." He had said shortly before, "I leave the world, and go to the Father;" now He says, "The Father is with me." Who goes to him who is with him? This is a word to him that understandeth, a proverb to him that understandeth not: and yet in such way that what at present is unintelligible to babes, is in some sort sucked in; and even though it yield them not solid food, which they cannot as yet receive, it denies them not at least a milky diet.

But on the occasion of His apprehension, not only did they outwardly abandon His bodily presence, but they mentally abandoned their faith. And to this it is that His words have reference, "Do ye now believe? Behold, the hour cometh, that ye shall be scattered to your own, and shall leave me:" as if He had said, You will then be so confounded as to leave behind you even what you now believe. For they fell into such despair and such a death, so to speak, of their old faith, as was apparent in the case of Cleophas, who, after His resurrection, unaware that he was speaking with Himself, and narrating what had befallen Him, said, "We trusted that it had been He who should have redeemed Israel." That was the way in which they then left Him, abandoning even the very faith wherewith they had formerly believed in Him.

(Tr. ciii) Lastly, He reminds them of their weak tender age in respect of the inner man. Jesus answered them, Do ye now believe?

Which can be understood in two ways, either as reproaching, or affirming. If the former, the meaning is, Ye have awaked somewhat late to belief, for behold the hour cometh, yea is now come, that ye shall be scattered every man to his home. If the latter, it is, That which ye believe is true, but behold the hour cometh, &c.
