Sotah, Chapter Seven, Mishnah 1. This chapter deals with things that halachah requires a person to actually say. The Torah demands that we recite certain texts, and some of them may be said in any language, while others may be said only in Hebrew. Our Mishnah opens with the list of those that may be said in any language: "Eilu ne'emarin b'chol lashon" - the following are said in any language.
The Mishnah opens with the passage of the sotah, and in this way the whole chapter is tied to the tractate: since the passage of the sotah is said in any language, the Mishnah goes on to list a series of other items that have no connection to sotah, apart from the fact that they too are said in any language.
The items that are said in any language:
Parashas sotah - the kohen's words to the woman and the oath he administers to her, as part of the procedure for a woman suspected of infidelity, may be said in any language.
Viduy ma'aser - after the third year of the shemittah cycle, and likewise after the sixth year, a person is required to clear all the tithes out of his house: some he must destroy, and some he must give to the parties to whom they belong, to the Levi and to the poor. Along with this he must recite the declaration spelled out in Parashas Ki Savo, and this is done at Pesach time following the third year (which is by then already the fourth year) and following the sixth year (which is by then already the seventh year, the shemittah year). In this declaration a person states that he has removed those items that are holy, and has given the Levi and the poor what he is obligated to give. That entire passage may be recited in any language, even though the Torah writes it in Hebrew.
Kerias Shema - the recitation of Shema twice a day.
Tefillah - Shemoneh Esrei, the standing prayer that we recite.
Birkas HaMazon - "benching."
Shevuas ha'eidus - someone who believes that one witness or two witnesses have information relevant to his case, and is unable to get them to come and testify, may impose an oath upon them. They may deny having any information at all, and claim that this is why they are not coming; and if they swore falsely, they must bring a sacrifice. That entire passage of the oath of testimony is said in any language.
Shevuas hapikadon - one who makes a claim against his fellow, saying: I deposited this item with you, and the other denies it, an oath is imposed upon him. If he later admits that he swore falsely, he too must bring a sacrifice for that false oath. This oath as well is administered in any language.
In summary: in this Mishnah the tanna lists the items that are said in any language: the passage of the sotah, the tithe declaration, Kerias Shema, Tefillah, Birkas HaMazon, the oath of testimony and the oath concerning a deposit. Even though the Torah expressed them in Hebrew, they are valid in other languages as well.
Next we will deal with the things that may be said only in Hebrew.
