Passover

===Blessing for search of chametz and nullification of chametz===
Before the search is begun there is a special [[Berakhah|blessing]]. If several people or family members assist in the search then only one person, usually the head of that family recites the blessing having in mind to include everyone present:<ref name="ArtScroll Pesach Machzor" />

:Blessed are You, Hashem our God, King of the universe, Who has sanctified us with his commandments and has commanded us concerning the removal of chametz.

In Hebrew:

ברוך אתה י-הוה א-להינו מלך העולם אשר קדשנו במצותיו וצונו על בעור חמץ

(''berūkh otah, Adoynoy E-lohaynū, melekh ha-'ôlam, eser qedesh-nū be-mitsūtayu we-tsewinū 'al be-ôr ḥamets'')

The search is then usually conducted by the head of the household joined by his family including children under the supervision of their parents.

It is customary to turn off the lights and conduct the search by [[candle]]light, using a feather and a wooden spoon: candlelight effectively illuminates corners without casting shadows; the feather can dust crumbs out of their hiding places; and the wooden spoon which collects the crumbs can be burned the next day with the ''chametz''. However, most contemporary Jewish-Orthodox authorities permit using a flashlight, while some strongly encourage it due to the danger coupled with using a candle.

Because the house is assumed to have been thoroughly cleaned by the night before Passover, there is some concern that making a blessing over the search for ''chametz'' will be in vain (''bracha l'vatala'') if nothing is found. Thus, 10 morsels of bread or cereal smaller than the size of an olive are traditionally hidden throughout the house in order to ensure that some ''chametz'' will be found.

Upon conclusion of the search, with all the small pieces safely wrapped up and put in one bag or place, to be burned the next morning, the following is said:

: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.

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

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