4 In the name of our Lord Jesus Christ, you being gathered together, and my spirit, with the power of our Lord Jesus;
5 To deliver such a one to Satan for the destruction of the flesh, that the spirit may be saved in the day of our Lord Jesus Christ.
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.
