1 Corinthians 5:6–13

6 Your glorying is not good. Know you not that a little leaven corrupteth the whole lump?

7 Purge out the old leaven, that you may be a new paste, as you are unleavened. For Christ our pasch is sacrificed.

8 Therefore, let us feast, not with the old leaven, nor with the leaven of malice and wickedness: but with the unleavened bread of sincerity and truth.

9 I wrote to you in an epistle not to keep company with fornicators.

10 I mean not with the fornicators of this world or with the covetous or the extortioners or the servers of idols: otherwise you must needs go out of this world.

11 But now I have written to you, not to keep company, if any man that is named a brother be a fornicator or covetous or a server of idols or a railer or a drunkard or an extortioner: with such a one, not so much as to eat.

12 For what have I to do to judge them that are without? Do not you judge them that are within?

13 For them that are without, God will judge. Put away the evil one from among yourselves.
