A.T. Robertson Commentary 2 Corinthians 12:13

"For what is there wherein ye were made inferior to the rest of the churches, except [it be] that I myself was not a burden to you? forgive me this wrong." — 2 Corinthians 12:13 (ASV)

Wherein ye were made inferior (ο ησσωθητε). First aorist passive indicative of ησσοομα, the text of Aleph B D instead of the usual ηττηθητε from the common ητταομα to be inferior or less from the comparative ηττων. See ησσων in verse 15. Hο is the neuter accusative with the passive verb (Robertson, Grammar, p. 479).

Forgive me this wrong (χαρισασθε μο την αδικιαν ταυτην). Consummate irony to the stingy element in this church (cf. 11:9).
