Leaven (yeast) » Figurative » Of other evils
A little leaven doth leaven the whole lump of dough.
Your rejoicing is not good. Know ye not that a little leaven soureth the whole lump of dough? Purge therefore the old leaven, that ye may be new dough, as ye are sweet bread. For Christ our Easter lamb is offered up for us. Therefore let us keep holiday, not with old leaven, neither with the leaven of maliciousness and wickedness - but with the sweet bread of pureness and truth.
