Titus 1:13-16

13This testimony is true. Therefore rebuke them sharply, that they may be sound in the faith,

14not devoting themselves to Jewish myths and the commands of people who turn away from the truth.

15To the pure, all things are pure, but to the defiled and unbelieving, nothing is pure; but both their minds and their consciences are defiled.

16They profess to know God, but they deny him by their works. They are detestable, disobedient, unfit for any good work.
