Titus 1:13-15 New Revised Standard Version, Anglicised (NRSVA)
13 That testimony is true. For this reason rebuke them sharply, so that they may become sound in the faith, 14 not paying attention to Jewish myths or to commandments of those who reject the truth. 15 To the pure all things are pure, but to the corrupt and unbelieving nothing is pure. Their very minds and consciences are corrupted.
