Romans 2:20-24

²⁰An instructor of the foolish, a teacher of infants, having the form of knowledge and of truth in the law.

²¹Thou therefore that teachest another, teachest not thyself: thou that preachest that men should not steal, stealest:

²²Thou that sayest, men should not commit adultery, committest adultery: thou that abhorrest idols, committest sacrilege:

²³Thou that makest thy boast of the law, by transgression of the law dishonourest God.

²⁴(For the name of God through you is blasphemed among the Gentiles, as it is written.)k
