Romans 2:23 KJV

Thou therefore which teachest another, teachest thou not thyself? thou that preachest a man should not steal, dost thou steal?

Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?

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

For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
