What do Protestants believe about 1st Corinthians 7:12 and the infallibility and inspiration of Scripture?

### Background Protestants believe that all scripture is infallible (that it is incapable of error) and that it is inspired by God (that it is God-breathed and the words of God). In 1st Corinthians 7:10-13 (NRSV) Paul gives two commands. In the first command, Paul says that it is "**from the Lord**". In the second command, Paul interestingly says that it comes from himself and "**not [from] the Lord**". > To the married **I give this command—not I but the Lord**—that the wife > should not separate from her husband 11 (but if she does separate, let > her remain unmarried or else be reconciled to her husband) and that > the husband should not divorce his wife. > > **To the rest I say—I and not the Lord**—that if any brother has a wife > who is an unbeliever and she consents to live with him, he should not > divorce her. And if any woman has a husband who is an unbeliever > and he consents to live with her, she should not divorce the husband. ### Question Do Protestants believe that the command that Paul explicitly says is "not from the Lord" is both infallible and inspired? Is this portion of 1st Corinthians considered scripture by Protestants?
