1 Corinthians 5:1-13 KJV
It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father’s wife. And ye are puffed up, and have not rather mourned, that he that hath done this deed might be taken away from among you. For I verily, as absent in body, but present in spirit, have judged already, as though I were present, concerning him that hath so done this deed, In the name of our Lord Jesus Christ, when ye are gathered together, and my spirit, with the power of our Lord Jesus Christ, To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus. Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump? Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us: Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth. I wrote unto you in an epistle not to company with fornicators: Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world. But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat. For what have I to do to judge them also that are without? do not ye judge them that are within? But them that are without God judgeth. Therefore put away from among yourselves that wicked person.

And it came to pass, when the king had heard the words of the law, that he rent his clothes. And the king commanded Hilkiah, and Ahikam the son of Shaphan, and Abdon the son of Micah, and Shaphan the scribe, and Asaiah a servant of the king’s, saying, Go, enquire of the LORD for me, and for them that are left in Israel and in Judah, concerning the words of the book that is found: for great is the wrath of the LORD that is poured out upon us, because our fathers have not kept the word of the LORD, to do after all that is written in this book. And Hilkiah, and they that the king had appointed, went to Huldah the prophetess, the wife of Shallum the son of Tikvath, the son of Hasrah, keeper of the wardrobe; (now she dwelt in Jerusalem in the college:) and they spake to her to that effect.And she answered them, Thus saith the LORD God of Israel, Tell ye the man that sent you to me, Thus saith the LORD, Behold, I will bring evil upon this place, and upon the inhabitants thereof, even all the curses that are written in the book which they have read before the king of Judah: Because they have forsaken me, and have burned incense unto other gods, that they might provoke me to anger with all the works of their hands; therefore my wrath shall be poured out upon this place, and shall not be quenched. And as for the king of Judah, who sent you to enquire of the LORD, so shall ye say unto him, Thus saith the LORD God of Israel concerning the words which thou hast heard; Because thine heart was tender, and thou didst humble thyself before God, when thou heardest his words against this place, and against the inhabitants thereof, and humbledst thyself before me, and didst rend thy clothes, and weep before me; I have even heard thee also, saith the LORD. Behold, I will gather thee to thy fathers, and thou shalt be gathered to thy grave in peace, neither shall thine eyes see all the evil that I will bring upon this place, and upon the inhabitants of the same. So they brought the king word again.
Revelation 3:15-20 KJV
I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot. So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth. Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and blind, and naked: I counsel thee to buy of me gold tried in the fire, that thou mayest be rich; and white raiment, that thou mayest be clothed, and that the shame of thy nakedness do not appear; and anoint thine eyes with eyesalve, that thou mayest see. As many as I love, I rebuke and chasten: be zealous therefore, and repent. Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.

For if any be a hearer of the word, and not a doer, he is like unto a man beholding his natural face in a glass: For he beholdeth himself, and goeth his way, and straightway forgetteth what manner of man he was.
