rsv - 1Corinthians:5:7-8

rsv@1Corinthians:5:7 @ Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our paschal lamb, has been sacrificed.

rsv@1Corinthians:5:8 @ Let us, therefore, celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth.
