1 Corinthians 5:6-8

6 aYour boasting is not good. Do you not know that ba little leaven leavens the whole lump? 7Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed. 8Let us therefore celebrate the festival, cnot with the old leaven, dthe leaven of malice and evil, but with the unleavened bread of sincerity and truth.
