Matthieu 23:3
All therefore whatsoever they bid you observe, that observe and do; but do not ye after their works: for they say, and do not.
Ezechiel 33:31
And they come unto thee as the people cometh, and they sit before thee as my people, and they hear thy words, but they will not do them: for with their mouth they shew much love, but their heart goeth after their covetousness.
Romains 2:17-25
17
Behold, thou art called a Jew, and restest in the law, and makest thy boast of God,
18
And knowest his will, and approvest the things that are more excellent, being instructed out of the law;
19
And art confident that thou thyself art a guide of the blind, a light of them which are in darkness,
20
An instructor of the foolish, a teacher of babes, which hast the form of knowledge and of the truth in the law.
21
Thou therefore which teachest another, teachest thou not thyself? thou that preachest a man should not steal, dost thou steal?
22
Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?
23
Thou that makest thy boast of the law, through breaking the law dishonourest thou God?
24
For the name of God is blasphemed among the Gentiles through you, as it is written.
25
For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
Tite 1:16
They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.
