Now I tell you before it come, that, when it is come to pass, ye may believe that I am he.
Now, [ ap' (G575 ) arti (G737 ), rather, 'From henceforth'] I tell you before it come - consider yourselves as from this time fore-warned,
That, when it is come to pass - instead of being staggered,
Ye may believe that I am he - rather, confirmed in your faith: and indeed this did come to pass when they deeply needed such confirmation.
