1 Corinthians 5:7-9

New Testament for Everyone

⁷ Cleanse out the old leaven, so that you can be a new lump, the leaven-free lump you really are. It’s Passover-time, you see, and our Passover lamb—the Messiah, I mean—has already been sacrificed! ⁸ What we now have to do is to keep the festival properly: none of the leaven of the old life, and none of the leaven of depravity and wickedness, either. What we need is leaven-free bread, and that means sincerity and truth.

⁹ I wrote to you in the previous letter not to become associated with immoral people.
