Jewish prayer (Hebrew: תְּפִילָּה, tefilla [tfiˈla]; plural תְּפִילּוֹת tefillot [tfiˈlot]; Yiddish: תּפֿלה, romanized: tfile [ˈtfɪlə], plural תּפֿלות tfilles [ˈtfɪləs]; Yinglish: davening /ˈdɑːvənɪŋ/ from Yiddish דאַוון davn 'pray') is the prayer recitation that forms part of the observance of Rabbinic Judaism. These prayers, often with instructions and commentary, are found in the Siddur, the traditional Jewish prayer book.
Prayer, as a "service of the heart," is in principle a Torah-based commandment. It is mandatory for Jewish women and men. However, the rabbinic requirement to recite a specific prayer text does differentiate between men and women: Jewish men are obligated to recite three prayers each day within specific time ranges (zmanim), while, according to many approaches, women are only required to pray once or twice a day, and may not be required to recite a specific text.
