'Permitted' in the Bible

It is actually reported that sexual immorality exists among you, the kind of immorality that is not permitted even among the Gentiles, so that someone is cohabiting with his father's wife.

All [things] are permitted for me, but not all [things] are profitable. All [things] are permitted for me, but I will not be controlled by anything.

All [things] are permitted, but not all [things] are profitable. All [things] are permitted, but not all [things] build up.

Let your women keep silence in the churches: for it is not permitted unto them to speak; but they are commanded to be under obedience, as also saith the law.
