Titus 1:15 WEB

¹³  This testimony is true. For this cause, reprove them sharply, that they may be sound in the faith,

¹⁴  not paying attention to Jewish fables and commandments of men who turn away from the truth.

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

¹⁶  They profess that they know God, but by their works they deny him, being abominable, disobedient, and unfit for any good work.
