Pesachim 1:1 - 1:2

אור לארבעה עשר – the night of its morrow will be the fourteenth [of Nisan], and the Tanna [of our Mishnah] calls night, “light” in the manner that we call a blind person “capable of eye-sight,” and he took/used the more appropriate expression.

בודקין את החמץ – there are those who explain the reason of searching [for the Hametz/leavened products] in order that he not transgress “lest any [leaven] be found” (see Exodus 13:7: “[Throughout the seven days unleavened bread shall be eaten; no leavened bread shall be found with you,] and no leaven shall be [seen, literally] found/ולא יראה לך [in all your territory,) and “lest it (i.e., leaven) be seen” (see Exodus 12:19 – “שבעת ימים שאר לא ימצא בבתיכם” /”No leaven shall be found in your houses for seven days…”) if there would be leavened products in his home during Passover. And even though mere nullification is sufficient, we are suspicious lest he find a white and delicate bread (i.e., a roll) and he will reconsider his nullification and think about it to eat it and violate [the Biblical injunction of] “lest it be seen with you, lest it be found with you” (see Exodus 13:7 and Exodus 12:19 above). Therefore, we search for the leavened products in order that he may remove it from the world. And there are those who say that the reason for searching [for Hametz] is a decree lest he find leavened products in his house during Passover and would eat them, since he is not accustomed to abstain from them all the rest of the days of the year.

לאור הנר – In the Gemara ( Talmud Pesahim 2a), it derives that the search for Hametz must be by the light of a candle, since it is written here (Exodus 12:12: "שאר לא ימצא" / “no leaven shall be found” and it is written there (Genesis 44:12): “וימצא הגביע [באמתחת בנימן] / “and the goblet turned up in Benjamin’s bag,” Just as “something found” which is said there, is through searching, as it says, ‘And [the goblet] turned up,” so too, “something found” which is mentioned here, is through searching, and searching is done by a candle, as it is written (Proverbs 20:17)– "נר ה' נשמת אדם"/”The life-breath of man is the lamp (literally, “candle”) of God [revealing the innermost parts].” And they established, that the search is at night, since at night all the people are found in their homes, and the light of a candle is nicer for a search than during the day, for a lamp at noon – what good is it? But however, if he did not search [for Hametz] on the night of the fourteenth [of Nisan] and he searched on the fourteenth in the morning, he has to search also by the light of a candle.

ולמה אמרו – further on in our Mishnah

שתי שורות – of wine jugs that are arranged this one on top of that in the wine store-room/cellar one must search between them, for after we said [in the Mishnah], “every place where we don’t bring in Hametz, there is no need for a search,” why did they require of us to search there? And we respond: They did not say [that we do not have to search] other than in a store-room/cellar where we bring in leavened products/Hametz, like a store-room/cellar from which he supplies wine for his table and the sometimes when the servant stands to pour it and his bread is in his hand , and when the wine is finished, he enters into the store-room/cellar to bring wine.

שתי שורות על פני [כל] המרתף – It is way of those who store wine to arrange the wine jugs row by row until they fill all the floor of the store-room/cellar and you go pack and place wine jug on top of wine jug, so that lower rows will be like the upper rows up until the ceiling beam. And the two rows that the School of Shammai mentioned is the outermost row from the ground until the top of the beam, and goes back and searches [for Hametz] the uppermost wine jugs over the length and width of the store-room/cellar, and as a result, the two rows are like the Greek GAM/gamma, one row is standing up and the other row is lying down.

שתי שורות החיצונות – The highest row nearest the ceiling beam which looks out at the face of the opening which is lower than it. And those [jugs] which are inside [of this] do not require searching at all, and from the outermost [jugs] he does not search but only the two uppermost ones alone.

אין חוששין – when he searched his home in this corner and came to check the other corner, we should not suspect lest in the midst of my coming to this [corner], a mole dragged [hametz] from the checked place and I have to go back and re-check it, for if you come to fear for this, then behold, you also [have to check] from this courtyard to [the other] courtyard, one can say that I checked prior to my fellow and after my searching the mole brought Hametz from my fellow’s courtyard to my courtyard, and there is no end [to this].
