G4258–προαμαρτάνω–proamartanō

And that when I come again, my God may put me to shame among you, and I may have grief for those who have done wrong before and have had no regret for their unclean ways, and for the evil desires of the flesh to which they have given way.

προημαρτηκότων proēmartēkotōn “having sinned before”

I said before, and still say it before I come, as being present for the second time, though I am still away from you, to those who have done wrong before, and to all the others, that if I come again I will not have pity;

προημαρτηκόσιν proēmartēkosin “having sinned before”
