kjv@1Corinthians:5:6 @ Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump?
kjv@1Corinthians:5:7 @ 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:
kjv@1Corinthians:5:8 @ 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.
