Briefly

But in order not to delay you any further, I beg your indulgence to hear us briefly.

…that is, the mystery made known to me by revelation, as I have already written briefly.

I urge you, brothers, to bear with my word of exhortation, for I have only written to you briefly.

Through Silvanus, whom I regard as a faithful brother, I have written to you briefly, encouraging you and testifying that this is the true grace of God. Stand firm in it.
