SEARCHING FOR ḤAMETZ
Before searching for ḥametz on the night preceding Pesaḥ:
Blessed art thou, Lord our God, King of the universe, who hast sanctified us with thy commandments, and commanded us concerning the removal of leaven.
The formal search is concluded by this pronouncement:
Any kind of leaven in my possession which has escaped my notice, and which I have not removed, shall be regarded as nonexistent or as mere dust of the earth.
After burning the ḥametz on Evev Pesaḥ morning:
Any kind of leaven in my possession, whether or not I have seen it, whether or not I have removed it, shall be regarded as nonexistent or as mere dust of the earth.
ERUV TAVSHILIN
Recited over food on the eve of a festival that is followed by a Sabbath:
Blessed art thou, Lord our God, King of the universe, who hast sanctified us with thy commandments, and commanded us concerning the observance of eruv.
By means of this eruv may we be permitted to bake, cook, keep dishes warm, light Sabbath lights, and prepare during the festival all we need for the Sabbath—we and all Israelites that live in this town.
(
Hebrew characters) ("mixture of dishes") renders it permissible to prepare food on a holy day for use on the Sabbath which immediately follows it. The permission to prepare food on holy days is restricted to food required for those days; but if the preparation was begun before the holy day, it may be continued on the holy day itself. This is accomplished by symbolically singling out food for the Sabbath on the eve of the festival.
