1 Corinthians 5:7; 1 Corinthians 5:8

1 Corinthians 5:7

7 Get rid of the old yeast, so that you may be a new unleavened batch—as you really are. For Christ, our Passover lamb, has been sacrificed.

1 Corinthians 5:8

8 Therefore let us keep the Festival, not with the old bread leavened with malice and wickedness, but with the unleavened bread of sincerity and truth.
