3 Bible Verses about Feast Of Unleavened Bread

And seeing that it was pleasing to the Jews, he proceeded to apprehend Peter also, (in the days of unleavened bread:)

Do ye not know that a little leaven leaveneth the whole mass? 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. 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.
