Titus 1:13-15 New International Version - UK (NIVUK)
13 This saying is true. Therefore rebuke them sharply, so that they will be sound in the faith 14 and will pay no attention to Jewish myths or to the merely human commands of those who reject the truth. 15 To the pure, all things are pure, but to those who are corrupted and do not believe, nothing is pure. In fact, both their minds and consciences are corrupted.
