1 Corinthians 5
6 Your boasting is not good. Don't you know that a little yeast works through the whole batch of dough? 7 Get rid of the old yeast that you may be a new batch without yeast—as you really are. For Christ, our Passover lamb, has been sacrificed. 8 Therefore let us keep the Festival, not with the old yeast, the yeast of malice and wickedness, but with bread without yeast, the bread of sincerity and truth.
