1 Corinthians 5:6-8

Revised Geneva Translation

⁶ Your boasting is not good. Do you not know that a little leaven leavens the whole lump?

⁷ Therefore, purge the old leaven, that you may be a new lump, as you are unleavened. For Christ, our Passover, is sacrificed for us.

⁸ Therefore let us keep the feast, not with old leaven, nor in the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.
