“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.”
King James Version (KJV)
2Co 8:10 Herein I give [my] advice. Not a "commandment" (2Co 8:8), but advice. For this is expedient for you. That is, that it is expedient to complete the work begun "a year ago", or as we would say, "last year".
