Kavanah and Keva

(1) Shacharit [can be said] until midday. Rabbi Yehudah says until four hours into the day. Minchah [can be said] until the evening. Rabbi Yehudah says until the middle of the afternoon. Ma'ariv has no set time and Musaf can be said all day. Rabbi Yehudah says until seven hours into the day.

(3) Rabban Gamliel says: Every day a person must pray eighteen [blessings of Shemoneh Esrei]. Rabbi Yehoshua says: [One may say] an abbreviated [form of the] eighteen [blessings]. Rabbi Akiva says: If his prayer is fluent in his mouth, he must say eighteen; and if it is not -- an abbreviated eighteen.

(4) Rabbi Eliezer says: One who makes his prayer perfunctory, his prayer does not constitute supplications for grace. Rabbi Yehoshua says: One who is traveling in a dangerous place should offer a brief prayer [and] say: Save, God, Your people, the remnant of Israel; at every period of transition let their needs be before You. You are the Source of all blessing, God, Who heeds prayer.

Antoninus asked Our Holy Rabbi [Judah the Prince]: Is it permitted to pray at every hour? He said to him: It is forbidden. He said to him: Why? He said to him: Lest you treat the Most High with frivolity. He [Antoninus] was not persuaded [by this answer]. What did he do? He went to him early in the morning. He said to him: Peace be upon you. An hour later he came in to him. He said to him: [Imperator]! An hour later he said to him: Peace be upon to you, O King. He said to him: Why are you being disrespectful to the monarchy? He said to him: Let your ears hear what your mouth utters. If you, mere flesh and blood, say this in the case of someone who asks after you every hour, how much the more so in the case of one who is disrespectful to the Supreme Sovereign of Sovereigns, the Holy One of Blessing. Thus one should not bother the [Sovereign of Sovereigns] at every hour.

(1) If one was reading [Shema] in the Torah, and it came time to recite [Shema]: If he directed his mind [and intended to fulfill his obligation to recite Shema as he read it], he has fulfilled his obligation. And if not, he has not fulfilled his obligation. At the breaks [between sections of Shema], one may greet another out of honor and return a greeting, and in the middle [of a section], one may greet out of fear and return a greeting. These are the words of Rabbi Meir. Rabbi Yehuda says: In the middle, one may greet out of fear and return a greeting out of honor, and at the breaks, one may greet out of honor and return a greeting to any person.

(1) [One] should not stand up to pray unless he is in a serious frame of mind. The original pious ones used to wait one hour and then pray, in order to direct their hearts towards the Omnipresent. [While one is reciting Shemoneh Esrei,] even if the king greets him, he should not respond to him, and even if a snake wraps around his heel, he should not interrupt.

(12) And it came to pass, as she prayed long before the LORD, that Eli watched her mouth. (13) Now Hannah, she spoke in her heart; only her lips moved, but her voice could not be heard; therefore, Eli thought she had been drunken. (14) And Eli said unto her: ‘How long wilt thou be drunken? put away thy wine from thee.’ (15) And Hannah answered and said: ‘No, my lord, I am a woman of a sorrowful spirit; I have drunk neither wine nor strong drink, but I poured out my soul before the LORD. (16) Count not thy handmaid for a wicked woman: for out of the abundance of my complaint and my vexation have I spoken hitherto.’ (17) Then Eli answered and said: ‘Go in peace, and the God of Israel grant thy petition that thou hast asked of Him.’

We learned in the mishna that Rabbi Eliezer says: One whose prayer is fixed, his prayer is not supplication. The Gemara asks: What is the meaning of fixed in this context? Rabbi Ya’akov bar Idi said that Rabbi Oshaya said: It means anyone for whom his prayer is like a burden upon him, from which he seeks to be quickly unburdened. The Rabbis say: This refers to anyone who does not recite prayer in the language of supplication, but as a standardized recitation without emotion. Rabba and Rav Yosef both said: It refers to anyone unable to introduce a novel element, i.e., something personal reflecting his personal needs, to his prayer, and only recites the standard formula.

(1) To pray daily is an affirmative duty, as it is said, "And ye shall serve the Lord, your God" (Exodus 23:25). The service, here referred to, according to the teaching of tradition, is Prayer, as it is said, "And to serve Him with all your heart" (Deuteronomy 11:13), on which the sages commented, "What may be described as Service of the Heart? Prayer". The number of prayers is not prescribed in the Torah. No form of prayer is prescribed in the Torah. Nor does the Torah prescribe a fixed time for Prayer. Hence, women and slaves are under an obligation to pray, this being a duty, the fulfillment of which is independent of set periods.

(2) The obligation in this precept is that every person should daily, according to his ability, offer up supplication and prayer; first uttering praises of God, then, with humble supplication and petition ask for all that he needs, and finally offer praise and thanksgiving to the Eternal for the benefits already bestowed upon him in rich measure.

(3) One who was fluent, would offer up many prayers and supplications. If one was slow of speech, he would pray as he could and whenever he pleased. Thus also, the number of separate services depended on an individual's ability. One would pray once daily; others, several times in the day. All, however, turned during prayer to the Sanctuary, in whichever direction that might be. This was the uniform practice from the times of Moses to those of Ezra.

(4) When the people of Israel went into exile in the days of the wicked Nebucednezzar, they mingled with the Persians, Greeks and other nations. In those foreign countries, children were born to them, whose language was confused. Everyone's speech was a mixture of many tongues. No one was able, when he spoke, to express his thoughts adequately in any one language, otherwise than incoherently, as it is said, "And their children spoke half in the speech of Ashdod and they could not speak in the Jews' language, but according to the language of each people" (Nehemiah 13:24). Consequently, when anyone of them prayed in Hebrew, he was unable adequately to express his needs or recount the praises of God, without mixing Hebrew with other languages. When Ezra and his Council realized this condition, they ordained the Eighteen Benedictions in their present order. The first three blessings consist of praises of God and the last three, of thanksgiving to Him. The intermediate benedictions are petitions for the things which may stand as categories of all the desires of the individual and the needs of the community. The object aimed at was that these prayers should be in an orderly form in everyone's mouth, that all should learn them, and thus the prayer of those who were not expert in speech would be as perfect as that of those who had command of a chaste style. For the same reason, they arranged [in a fixed form] all the blessings and prayers for all Jews so that the substance of every blessing should be familiar and current in the mouth of one who is not expert in speech.

(5) Thus, too, they ordained that the Services of Prayer should be equal in number to the Sacrifices—two services of prayer daily, corresponding to the two daily offerings. And for the day on which an additional offering was ordained, they instituted a third prayer, corresponding to the additional offering. The Service which corresponds to the daily morning sacrifice is called the Morning Prayer. The Service which corresponds to the Afternoon Sacrifice is called the Afternoon Prayer, and the Service corresponding to the Additional offering is called the Additional Prayer.

(15) Concentration of the mind—how is this condition [to be fulfilled?] Any prayer uttered without mental concentration is not prayer. If a service has been recited without such concentration, it must be recited again devoutly. A person finds that his thoughts are confused and his mind is distracted: He may not pray till he has recovered his mental composure. Hence, on returning from a journey or if one is weary or distressed, it is forbidden to pray till his mind is composed. The sages said that he should wait three days till he is rested and his mind is calm, and then he recites the prayers.

(16) What is to be understood by concentration of the mind? The mind should be freed from all extraneous thoughts and the one who prays should realize that he is standing before the Divine Presence. He should therefore sit awhile before beginning his prayers, so as to concentrate his mind, and then pray in gentle tones, beseechingly, and not regard the service as a burden which he is carrying and which he will cast off and proceed on his way. He should, accordingly, also sit awhile, after concluding the prayers, and then leave. The ancient saints were wont to pause and meditate one hour before the service, one hour after the service and take one hour in its recital.

(1) If one has recited the Amidah without devotion, he should recite it again devoutly. If he, however, concentrated his attention during the recital of the first blessing, he need not read the prayer again. If one committed an error in one of the first three blessings, he has to turn back to the beginning of the Amidah. If he made a mistake in one of the last three blessings, he turns back to the blessing relating to the restoration of the Temple Service. If he made a mistake in one of the intermediate blessings, he turns back to the beginning of the blessing in which he made the mistake, and then continues the Service in regular order to the end. The reader, if he makes a mistake when reading the Amidah aloud, follows the same rules.
