1 Corinthians 5:6-8

Worsley(i) 6 Do ye not know that a little leaven leaveneth the whole mass? 7 Purge out therefore the old leaven, that ye may be a new mass, without leaven. For our paschal lamb, even Christ, was slain for us. 8 Wherefore let us keep the feast, not with the old leaven, nor with the leaven of malice and wickedness, but with the unleavening of sincerity and truth.
