'Incest' in the Bible

But if someone has caused [all this] sorrow, he has caused it not to me, but in some degree—not to put it too severely—[he has distressed and grieved] all of you.

For [you can look back and] see what an earnestness and authentic concern this godly sorrow has produced in you: what vindication of yourselves [against charges that you tolerate sin], what indignation [at sin], what fear [of offending God], what longing [for righteousness and justice], what passion [to do what is right], what readiness to punish [those who sin and those who tolerate sin]! At every point you have proved yourselves to be innocent in the matter.
