Titus 1:13-16

13This testimony is true. For this reason, rebuke them sharply, so that they may be sound in the faith

14and may not pay attention to Jewish myths and the commands of people who reject the truth.

15To the pure, everything is pure, but to those who are defiled and unbelieving nothing is pure; in fact, both their mind and conscience are defiled.

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