1 Corinthians 5:6-8 Your boasting is no credit to you. Do you not know that a morsel of dough will leaven the whole lump?

Moffatt⁽ⁱ⁾ ⁶ Your boasting is no credit to you. Do you not know that a morsel of dough will leaven the whole lump? ⁷ Clean out the old dough that you may be a fresh lump. For you are free from the old leaven; Christ our paschal lamb has been sacrificed. ⁸ So let us celebrate our festival, not with any old leaven, not with vice and evil, but with the unleavened bread of innocence and integrity.
