False prophets and false teachers

If there arise among you a prophet, or a dreamer of dreams, and gives you a sign or a wonder,
And the sign or the wonder come to pass, whereof he spoke unto you, saying, Let us go after other gods, which you have not known, and let us serve them;
You shall not hearken unto the words of that prophet, or that dreamer of dreams: for the LORD your God proves you, to know whether all of you love the LORD your God with all your heart and with all your soul.
Deuteronomy 13:1-3

His watchmen are blind: they are all ignorant, they are all dumb dogs, they cannot bark; sleeping, lying down, loving to slumber.
Yea, they are greedy dogs which can never have enough, and they are shepherds that cannot understand: they all look to their own way, every one for his gain, from his quarter.
Isaiah 56:10-11

Then said I, Ah, Lord GOD! behold, the prophets say unto them, All of you shall not see the sword, neither shall all of you have famine; but I will give you assured peace in this place.
Then the LORD said unto me, The prophets prophesy lies in my name: I sent them not, neither have I commanded them, neither spoke unto them: they prophesy unto you a false vision and divination, and a thing of nothing, and the deceit of their heart.
Jeremiah 14:13-14

Thus says 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.
They say still unto them that despise me, The LORD has said, All of you shall have peace; and they say unto every one that walks after the imagination of his own heart, No evil shall come upon you.
Jeremiah 23:16-17

I have heard what the prophets said, that prophesy lies in my name, saying, I have dreamed, I have dreamed.
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;
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.
Behold, I am against the prophets, says the LORD, that use their tongues, and say, He says.
Behold, I am against them that prophesy false dreams, says the LORD, and do tell them, and cause my people to go astray by their lies, and by their levity; yet I sent them not, nor commanded them: therefore they shall not profit this people at all, says the LORD.
Jeremiah 23:25-27,31-32

For thus says 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 all of you cause to be dreamed.
For they prophesy falsely unto you in my name: I have not sent them, says the LORD.
Jeremiah 29:8-9

Your prophets have seen vain and foolish things for you: and they have not discovered yours iniquity, to turn away your captivity; but have seen for you false burdens and causes of banishment.
Lamentations 2:14

Thus says the Lord GOD; Woe unto the foolish prophets, that follow their own spirit, and have seen nothing!
O Israel, your prophets are like the foxes in the deserts.
All of you 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.
They have seen vanity and lying divination, saying, The LORD says: and the LORD has not sent them: and they have made others to hope that they would confirm the word.
Have all of you not seen a vain vision, and have all of you not spoken a lying divination, whereas all of you say, The LORD says it; although it be I have not spoken?
Therefore thus says the Lord GOD; Because all of you have spoken vanity, and seen lies, therefore, behold, I am against you, says the Lord GOD.
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 all of you shall know that I am the Lord GOD.
Ezekiel 13:3-9

Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.
Wherefore by their fruits all of you shall know them.
Not every one that says unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that does the will of my Father which is in heaven.
Many will say to me in that day, Lord, Lord, have we not prophesied in your name? and in your name have cast out devils? and in your name done many wonderful works?
And then will I profess unto them, I never knew you: depart from me, all of you that work iniquity.
Matthew 7:15,20-23

And many false prophets shall rise, and shall deceive many.
Matthew 24:11

For there shall arise false Christs, and false prophets, and shall show great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
Matthew 24:24

But there was a certain man, called Simon, which in time past in the same city used sorcery, and bewitched the people of Samaria, giving out that himself was some great one:
To whom they all gave heed, from the least to the greatest, saying, This man is the great power of God.
And to him they had regard, because that of long time he had bewitched them with sorceries.
And when Simon saw that through laying on of the apostles' hands the Holy Spirit was given, he offered them money,
Saying, Give me also this power, that on whomsoever I lay hands, he may receive the Holy Spirit.
Acts 8:9-11,18-19

For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.
And no marvel; for Satan himself is transformed into an angel of light.
Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
2 Corinthians 11:13-15

Even him, whose coming is after the working of Satan with all power and signs and lying wonders,
And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
And for this cause God shall send them strong delusion, that they should believe a lie:
That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
2 Thessalonians 2:9-12

But there were false prophets also among the people, even as there shall be false teachers among you, who privately shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.
2 Peter 2:1

Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
1 John 4:1

For there are certain men crept in unexpectedly, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ.
