Titus 1:8-10

Amplified Bible

⁸ And he must be hospitable [to believers, as well as strangers], a lover of what is good, sensible (upright), fair, devout, self-disciplined [above reproach—whether in public or in private]. ⁹ He must hold firmly to the trustworthy word [of God] as it was taught to him, so that he will be able both to give accurate instruction in sound [reliable, error-free] doctrine and to refute those who contradict [it by explaining their error].

¹⁰ For there are many rebellious men who are empty talkers [just windbags] and deceivers; especially those of the circumcision [those Jews who insist that Gentile believers must be circumcised and keep the Law in order to be saved].
