A.T. Robertson Commentary 2 Corinthians 1:6

"But whether we are afflicted, it is for your comfort and salvation; or whether we are comforted, it is for your comfort, which worketh in the patient enduring of the same sufferings which we also suffer:" — 2 Corinthians 1:6 (ASV)

Whether (ειτε)

--or (ειτε). The alternatives in Paul's experience (afflicted θλιβομεθα, comforted παρακαλουμεθα) work out for their good when they are called on to endure like sufferings "which we also suffer" (ων κα ημεις πασχομεν). The relative ων is attracted from neuter accusative plural α to genitive case of the antecedent παθηματων (sufferings).
