'Impurity' in the Bible

[I am afraid] lest [when I] come again my God will humiliate me {in your presence}, and I will grieve over many of those who sinned previously and have not repented because of their impurity and sexual immorality and licentiousness that they have practiced.

Now the deeds of the flesh are evident, which are sexual immorality, impurity, licentiousness,

For our exhortation [is] not from error or from impurity or with deceit,

For God did not call us to impurity, but in holiness.
