Passover

===Burning and nullification of leaven===
On the morning of the 14th of [[Nisan]], any leavened products that remain in the householder's possession, along with the 10 morsels of bread from the previous night's search, are burned (''s'rayfat chametz''). The head of the household repeats the declaration of ''biyur chametz'', declaring any ''chametz'' that may not have been found to be null and void "as the dust of the earth":

:Any chametz or leaven that is in my possession which I have not seen and have not removed and do not know about should be annulled and become ownerless like the dust of the earth.

The original declaration, as recited in [[Aramaic language|Aramaic]], is:<ref name="ArtScroll Pesach Machzor" />

כל חמירא וחמיעא דאכא ברשותי דלא חמתה ודלא בערתה ודלא ידענא לה לבטל ולהוי הפקר כעפרא דארעא

Should more ''chametz'' actually be found in the house during the Passover holiday, it must be burnt as soon as possible.

Unlike ''chametz'', which can be eaten any day of the year except during Passover, kosher for Passover foods can be eaten year-round. They need not be burnt or otherwise discarded after the holiday ends.

The historic "Paschal lamb" [[Passover sacrifice]] (''Korban Pesach'') has not been brought following the Romans' destruction of the [[Second Temple|Second Jewish temple]] approximately two thousand years ago, and it is therefore still not part of the modern Jewish holiday.

In the times when the Jewish Temples stood, the lamb was slaughtered and cooked on the evening of Passover and was completely consumed before the morning as described in Exodus 12:3–11.<ref>{{bibleverse||Exodus|12:3–11|HE}}</ref>
