KJV:
And herein I give my advice: for this is expedient for you, who have begun before, not only to do, but also to be forward a year ago.
NASB:
I give my opinion in this matter, for this is to your advantage, who were the first to begin a year ago not only to do this, but also to desire to do it.
KJV:
For I know the forwardness of your mind, for which I boast of you to them of Macedonia, that Achaia was ready a year ago; and your zeal hath provoked very many.
NASB:
for I know your readiness, of which I boast about you to the Macedonians, namely, that Achaia has been prepared since last year, and your zeal has stirred up most of them.
