Titus 1:14-16
1:14 and not pay attention to Jewish myths and commands of people who reject the truth.
1:15 All is pure to those who are pure. But to those who are corrupt and unbelieving, nothing is pure, but both their minds and consciences are corrupted.
1:16 They profess to know God but with their deeds they deny him, since they are detestable, disobedient, and unfit for any good deed.
