Theophylact of Ohrid

That is: for me, the great and praiseworthy reward is in not using my right to take, not using it at all. For the word κατάχρησις (which in other cases means misuse) he used here in the sense of use (χρήσις) in general. He everywhere calls the taking "right," in order to show that even those who took were not sinning in the least. He said "in the gospel" in order to show that whoever preaches the gospel and labors should take, but whoever does not, should not.
