6 Your boasting is not good. Do ye not know that a little leaven leavens the whole lump?
7 Purge out the old leaven, that ye may be a new lump, according as ye are unleavened. For also our passover, Christ, has been sacrificed;
8 so that let us celebrate the feast, not with old leaven, nor with leaven of malice and wickedness, but with unleavened bread of sincerity and truth.
9 I have written to you in the epistle not to mix with fornicators;
10 not altogether with the fornicators of this world, or with the avaricious and rapacious, or idolaters, since then ye should go out of the world.
11 But now I have written to you, if any one called brother be fornicator, or avaricious, or idolater, or abusive, or a drunkard, or rapacious, not to mix with him; with such a one not even to eat.
12 For what have I to do with judging those outside also? ye, do not ye judge them that are within?
