ISB ~ 2 Corinthians 12 v16

crafty, you say:Suspicions were apparently raised that Paul was mishandling the funds of the Jerusalem collection (chaps. 8-9). Critics probably accused him of secretly pocketing some of the money for himself, even though he appeared to live in poverty while among them (11:9).

These accusations were empty:Paul’s conscience was clear (1:12) because his conduct was irreproachable (4:2).See note on 2 Cor 8:21.
