4 In the name of our Lord Jesus Christ, when ye are gathered together, and my spirit, with the power of our Lord Jesus Christ,
5 let such a one be delivered unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus.
6 Your glorying is not good. Know ye not that a little leaven leavens the whole lump?
7 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;
8 therefore let us celebrate the feast, not in the old leaven, neither in the leaven of malice and wickedness, but in the unleavened bread of sincerity and truth.
9 I wrote unto you in an epistle not to associate with fornicators,
10 yet not altogether with the fornicators of this world or with the covetous or extortioners or with idolaters, for then ye would need to go out of the world.
