while they themselves also, with supplication on your behalf, long after you by reason of the exceeding grace of God in you.

While their hearts go out to you in love and in prayer for you, because of the great grace of God which is in you.

και δια της υπερ υμων δεησεως αυτων, οιτινες σας επιποθουσι δια την προς εσας υπερβαλλουσαν χαριν του Θεου.

And by their prayer for you, which long after you for the exceeding grace of God in you.
