1 Corinthians 5:6-8

Christian Standard Bible

⁶ Your boasting is not good. Don’t you know that a little leaven^[a](A) leavens the whole batch of dough?^{(B) 7} Clean out the old leaven so that you may be a new unleavened batch, as indeed you are. For Christ our Passover lamb^(C) has been sacrificed.^{[b] 8} Therefore, let us observe the feast, not with old leaven or with the leaven of malice and evil,^(D) but with the unleavened bread of sincerity and truth.
