1 Corinthians 5:7-9

New Matthew Bible

⁷ Purge therefore the old leaven, so that you may be new dough, as you are sweet bread. For Christ our Passover lamb is offered up for us. ⁸ Therefore let us keep holy day – not with old leaven, neither with the leaven of immorality and wickedness, but with the sweet bread of pureness and truth.

⁹ I wrote to you in an epistle that you should not keep company with fornicators.
