Be not deceived: evil communications corrupt good manners.

Know ye not that a little leaven leaveneth the whole lump? Purge out therefore the old leaven.

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 idolators; for then must we needs go out of the world.

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.

That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world.

In a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some to honour, and some to dishonour.

The fear of the Lord is to hate evil.—Abhor that which is evil.—Abstain from all appearance of evil.—Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled.

If I regard iniquity in my heart, the Lord will not hear me.

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.—Let a man examine himself, and so let him eat of that bread, and drink of that cup.

Let every one that nameth the name of Christ depart from iniquity.—Such an high priest became us, who is holy, harmless, undefiled, separate from sinners.—In him is no sin.
