Romans 15:18

“For I will not dare to speak of any of those things, etc..] He suggests that the false teachers did speak of things which were not done by them at all, and much less were what Christ had done by them; and signifies that he was a conscientious man, and could speak nothing but what was truth; his conscience would not suffer him, nor could he allow himself to make mention of anything, that was not done by him, as if it was; nor of anything that was done by himself, nor of anything that was done, as if it was done by himself, but as it was wrought by Christ; nor had he any need to speak of any other things which he had wrought himself, as he could not of what he had not wrought at all; or, as he…”
