(I Corinthians 14:32-33 [KJV])
[32] And the spirits of the prophets are subject to the prophets.
[33] For God is not the author of confusion, but of peace, as in all churches of the saints.
(Deuteronomy 18:17-22 [KJV])
[17] And the LORD said unto me, They have well spoken that which they have spoken.
[18] I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him.
[19] And it shall come to pass, that whosoever will not hearken unto my words which he shall speak in my name, I will require it of him.
[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.
(I John 4:1-6 [KJV])
[1] Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
[2] Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God:
[3] And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.
[4] Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world.
[5] They are of the world: therefore speak they of the world, and the world heareth them.
[6] We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.
(Matthew 7:15-20 KJV )
[15] Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves.
[16] Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
[17] Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
[18] A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
[19] Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
[20] Wherefore by their fruits ye shall know them.
(Jeremiah 5:31 [KJV]) The prophets prophesy falsely, and the priests bear rule by their means; and my people love to have it so: and what will ye do in the end thereof?
(Jeremiah 6:13 [KJV]) For from the least of them even unto the greatest of them every one is given to covetousness; and from the prophet even unto the priest every one dealeth falsely.
(Jeremiah 8:10 [KJV]) Therefore will I give their wives unto others, and their fields to them that shall inherit them: for every one from the least even unto the greatest is given to covetousness, from the prophet even unto the priest every one dealeth falsely.
(Jeremiah 14:14 [KJV]) Then the LORD said unto me, The prophets prophesy lies in my name: I sent them not, neither have I commanded them, neither spake unto them: they prophesy unto you a false vision and divination, and a thing of nought, and the deceit of their heart.
(Jeremiah 23:31-33 [KJV])
[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.
(Jeremiah 29:8-9 [KJV])
[8] For thus saith the LORD of hosts, the God of Israel; Let not your prophets and your diviners, that be in the midst of you, deceive you, neither hearken to your dreams which ye cause to be dreamed.
[9] For they prophesy falsely unto you in my name: I have not sent them, saith the LORD.´
(Jeremiah 37:13-14 [KJV])
[13] And when he was in the gate of Benjamin, a captain of the ward was there, whose name was Irijah, the son of Shelemiah, the son of Hananiah; and he took Jeremiah the prophet, saying, Thou fallest away to the Chaldeans.
[14] Then said Jeremiah, It is false; I fall not away to the Chaldeans. But he hearkened not to him: so Irijah took Jeremiah, and brought him to the princes.
(Lamentations 2:14 [KJV]) Thy prophets have seen vain and foolish things for thee: and they have not discovered thine iniquity, to turn away thy captivity; but have seen for thee false burdens and causes of banishment.
(Micah 2:11 [KJV]) If a man walking in the spirit and falsehood do lie, saying, I will prophesy unto thee of wine and of strong drink; he shall even be the prophet of this people.
(Matthew 5:11-12 [KJV])
[11] Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake.
[12] Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you.
(Matthew 24:11 [KJV]) And many false prophets shall rise, and shall deceive many.
(Matthew 24:24 [KJV]) For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
(Luke 6:26 [KJV]) Woe unto you, when all men shall speak well of you! for so did their fathers to the false prophets.
(Acts 13:6-11 [KJV])
[6] And when they had gone through the isle unto Paphos, they found a certain sorcerer, a false prophet, a Jew, whose name was Bar–jesus:
[7] Which was with the deputy of the country, Sergius Paulus, a prudent man; who called for Barnabas and Saul, and desired to hear the word of God.
[8] But Elymas the sorcerer (for so is his name by interpretation) withstood them, seeking to turn away the deputy from the faith.
[9] Then Saul, (who also is called Paul,) filled with the Holy Ghost, set his eyes on him,
[10] And said, O full of all subtilty and all mischief, thou child of the devil, thou enemy of all righteousness, wilt thou not cease to pervert the right ways of the Lord?
[11] And now, behold, the hand of the Lord is upon thee, and thou shalt be blind, not seeing the sun for a season. And immediately there fell on him a mist and a darkness; and he went about seeking some to lead him by the hand.
(II Peter 2:1-3 [KJV])
[1] But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.
[2] And many shall follow their pernicious ways; by reason of whom the way of truth shall be evil spoken of.
[3] And through covetousness shall they with feigned words make merchandise of you: whose judgment now of a long time lingereth not, and their damnation slumbereth not.
(Revelation of John 16:13 [KJV]) And I saw three unclean spirits like frogs come out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet.
(Revelation of John 19:20 [KJV]) And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
(Revelation of John 20:10 [KJV]) And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
