1 Corinthians 5:6-8

Common English Bible

⁶ Your bragging isn’t good! Don’t you know that a tiny grain of yeast makes a whole batch of dough rise? ⁷ Clean out the old yeast so you can be a new batch of dough, given that you’re supposed to be unleavened bread. Christ our Passover lamb has been sacrificed, ⁸ so let’s celebrate the feast with the unleavened bread of honesty and truth, not with old yeast or with the yeast of evil and wickedness.
