1 Corinthians 5:7; 1 Corinthians 5:8

1 Corinthians 5:7

7 Clean out the old leaven so that you may be a new lump, just as you are in fact unleavened. For Christ our Passover also has been sacrificed.

1 Corinthians 5:8

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