{In abasing myself} (emauton tapein(936e)). Humbling myself by
making tents for a living while preaching in Corinth. He is
ironical still about "doing a sin" (hamartian epoi(8873)a). {For
nought} (d(9372)ean). _Gratis_. Accusative of general reference,
common adverb. It amounts to sarcasm to ask if he did a sin in
preaching the gospel free of expense to them "that ye may be
exalted."
