1Jude, the servant of Jesus Christ, and brother of James, to them that are sanctified by God the Father, and preserved in Jesus Christ, and called:
2Mercy unto you, and peace, and love, be multiplied.
3Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.
4For there are certain men crept in unawares, 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.
5I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not.
6And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.
7Even as Sodom and Gomorrah, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.
8Likewise also these filthy dreamers defile the flesh, despise dominion, and speak evil of dignities.
9Yet Michael the archangel, when contending with the devil he disputed about the body of Moses, durst not bring against him a railing accusation, but said, The Lord rebuke thee.
10But these speak evil of those things which they know not: but what they know naturally, as brute beasts, in those things they corrupt themselves.
11Woe unto them! for they have gone in the way of Cain, and ran greedily after the error of Balaam for reward, and perished in the gainsaying of Core.
12These are spots in your feasts of charity, when they feast with you, feeding themselves without fear: clouds they are without water, carried about of winds; trees whose fruit withereth, without fruit, twice dead, plucked up by the roots;
13Raging waves of the sea, foaming out their own shame; wandering stars, to whom is reserved the blackness of darkness for ever.
14And Enoch also, the seventh from Adam, prophesied of these, saying, Behold, the Lord cometh with ten thousands of his saints,
15To execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds which they have ungodly committed, and of all their hard speeches which ungodly sinners have spoken against him.
16These are murmurers, complainers, walking after their own lusts; and their mouth speaketh great swelling words, having men’s persons in admiration because of advantage.
17But, beloved, remember ye the words which were spoken before of the apostles of our Lord Jesus Christ;
18How that they told you there should be mockers in the last time, who should walk after their own ungodly lusts.
19These be they who separate themselves, sensual, having not the Spirit.
20But ye, beloved, building up yourselves on your most holy faith, praying in the Holy Ghost,
21Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life.
22And of some have compassion, making a difference:
23And others save with fear, pulling them out of the fire; hating even the garment spotted by the flesh.
24Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy,
25To the only wise God our Saviour, be glory and majesty, dominion and power, both now and ever. Amen.
2 Peter 2
1But 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.
2And many shall follow their pernicious ways; by reason of whom the way of truth shall be evil spoken of.
3And 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.
4For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment;
5And spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly;
6And turning the cities of Sodom and Gomorrah into ashes condemned them with an overthrow, making them an example unto those that after should live ungodly;
7And delivered just Lot, vexed with the filthy conversation of the wicked:
8(For that righteous man dwelling among them, in seeing and hearing, vexed his righteous soul from day to day with their unlawful deeds;)
9The Lord knoweth how to deliver the godly out of temptations, and to reserve the unjust unto the day of judgment to be punished:
10But chiefly them that walk after the flesh in the lust of uncleanness, and despise government. Presumptuous are they, self willed, they are not afraid to speak evil of dignities.
11Whereas angels, which are greater in power and might, bring not railing accusation against them before the Lord.
12But these, as natural brute beasts, made to be taken and destroyed, speak evil of the things that they understand not; and shall utterly perish in their own corruption;
13And shall receive the reward of unrighteousness, as they that count it pleasure to riot in the day time. Spots they are and blemishes, sporting themselves with their own deceivings while they feast with you;
14Having eyes full of adultery, and that cannot cease from sin; beguiling unstable souls: an heart they have exercised with covetous practices; cursed children:
15Which have forsaken the right way, and are gone astray, following the way of Balaam the son of Bosor, who loved the wages of unrighteousness;
16But was rebuked for his iniquity: the dumb ass speaking with man’s voice forbade the madness of the prophet.
17These are wells without water, clouds that are carried with a tempest; to whom the mist of darkness is reserved for ever.
18For when they speak great swelling words of vanity, they allure through the lusts of the flesh, through much wantonness, those that were clean escaped from them who live in error.
19While they promise them liberty, they themselves are the servants of corruption: for of whom a man is overcome, of the same is he brought in bondage.
20For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.
21For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.
22But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire.
