Deuteronomy 18.20-22

20 But the prophet, which shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die.

21 And if thou say in thine heart, How shall we know the word which the LORD hath not spoken?

22 When a prophet speaketh in the name of the LORD, if the thing follow not, nor come to pass, that is the thing which the LORD hath not spoken, but the prophet hath spoken it presumptuously: thou shalt not be afraid of him.

Jeremiah 23.16-40

16 Thus saith the LORD of hosts, Hearken not unto the words of the prophets that prophesy unto you: they make you vain: they speak a vision of their own heart, and not out of the mouth of the LORD.

17 They say still unto them that despise me, The LORD hath said, Ye shall have peace; and they say unto every one that walketh after the imagination of his own heart, No evil shall come upon you.

18 For who hath stood in the counsel of the LORD, and hath perceived and heard his word? who hath marked his word, and heard it?

19 Behold, a whirlwind of the LORD is gone forth in fury, even a grievous whirlwind: it shall fall grievously upon the head of the wicked.

20 The anger of the LORD shall not return, until he have executed, and till he have performed the thoughts of his heart: in the latter days ye shall consider it perfectly.

21 I have not sent these prophets, yet they ran: I have not spoken to them, yet they prophesied.

22 But if they had stood in my counsel, and had caused my people to hear my words, then they should have turned them from their evil way, and from the evil of their doings.

23 Am I a God at hand, saith the LORD, and not a God afar off?

24 Can any hide himself in secret places that I shall not see him? saith the LORD. Do not I fill heaven and earth? saith the LORD.

25 I have heard what the prophets said, that prophesy lies in my name, saying, I have dreamed, I have dreamed.

26 How long shall this be in the heart of the prophets that prophesy lies? yea, they are prophets of the deceit of their own heart;

27 Which think to cause my people to forget my name by their dreams which they tell every man to his neighbour, as their fathers have forgotten my name for Baal.

28 The prophet that hath a dream, let him tell a dream; and he that hath my word, let him speak my word faithfully. What is the chaff to the wheat? saith the LORD.

29 Is not my word like as a fire? saith the LORD; and like a hammer that breaketh the rock in pieces?

30 Therefore, behold, I am against the prophets, saith the LORD, that steal my words every one from his neighbour.

31 Behold, I am against the prophets, saith the LORD, that use their tongues, and say, He saith.

32 Behold, I am against them that prophesy false dreams, saith the LORD, and do tell them, and cause my people to err by their lies, and by their lightness; yet I sent them not, nor commanded them: therefore they shall not profit this people at all, saith the LORD.

33 And when this people, or the prophet, or a priest, shall ask thee, saying, What is the burden of the LORD? thou shalt then say unto them, What burden? I will even forsake you, saith the LORD.

34 And as for the prophet, and the priest, and the people, that shall say, The burden of the LORD, I will even punish that man and his house.

35 Thus shall ye say every one to his neighbour, and every one to his brother, What hath the LORD answered? and, What hath the LORD spoken?

36 And the burden of the LORD shall ye mention no more: for every man’s word shall be his burden; for ye have perverted the words of the living God, of the LORD of hosts our God.

37 Thus shalt thou say to the prophet, What hath the LORD answered thee? and, What hath the LORD spoken?

38 But since ye say, The burden of the LORD; therefore thus saith the LORD; Because ye say this word, The burden of the LORD, and I have sent unto you, saying, Ye shall not say, The burden of the LORD;

39 Therefore, behold, I, even I, will utterly forget you, and I will forsake you, and the city that I gave you and your fathers, and cast you out of my presence:

40 And I will bring an everlasting reproach upon you, and a perpetual shame, which shall not be forgotten.

Ezekiel 13.1-10

1 And the word of the LORD came unto me, saying,

2 Son of man, prophesy against the prophets of Israel that prophesy, and say thou unto them that prophesy out of their own hearts, Hear ye the word of the LORD;

3 Thus saith the Lord GOD; Woe unto the foolish prophets, that follow their own spirit, and have seen nothing!

4 O Israel, thy prophets are like the foxes in the deserts.

5 Ye have not gone up into the gaps, neither made up the hedge for the house of Israel to stand in the battle in the day of the LORD.

6 They have seen vanity and lying divination, saying, The LORD saith: and the LORD hath not sent them: and they have made others to hope that they would confirm the word.

7 Have ye not seen a vain vision, and have ye not spoken a lying divination, whereas ye say, The LORD saith it; albeit I have not spoken?

8 Therefore thus saith the Lord GOD; Because ye have spoken vanity, and seen lies, therefore, behold, I am against you, saith the Lord GOD.

9 And mine hand shall be upon the prophets that see vanity, and that divine lies: they shall not be in the assembly of my people, neither shall they be written in the writing of the house of Israel, neither shall they enter into the land of Israel; and ye shall know that I am the Lord GOD.

10 Because, even because they have seduced my people, saying, Peace; and there was no peace; and one built up a wall, and, lo, others daubed it with untempered morter:

Matthew 23.5-12

5 But all their works they do for to be seen of men: they make broad their phylacteries, and enlarge the borders of their garments,

6 And love the uppermost rooms at feasts, and the chief seats in the synagogues,

7 And greetings in the markets, and to be called of men, Rabbi, Rabbi.

8 But be not ye called Rabbi: for one is your Master, even Christ; and all ye are brethren.

9 And call no man your father upon the earth: for one is your Father, which is in heaven.

10 Neither be ye called masters: for one is your Master, even Christ.

11 But he that is greatest among you shall be your servant.

12 And whosoever shall exalt himself shall be abased; and he that shall humble himself shall be exalted.
