3 Bible Verses about Feast Of Unleavened Bread

Within two days was the feast of the passover, and of unleavened bread. and the chief priests, with the Scribes, contriv'd how they might seize Jesus by surprize, and put him to death.

and perceiving that the Jews were pleas'd with this, he proceeded to secure Peter during the feast of unleavened bread:

Your levity is very indecent: don't you know that a little leaven infects the whole mass? purge out the old leaven, that you may be a new mass, since you should be without leaven. for Christ our paschal lamb has been sacrificed for us. therefore let us keep the feast, not with old leaven, the leaven of malice and wickedness; but with unaffected sincerity and truth.
