The Thirteen Attributes of Mercy or Shelosh-'Esreh Middot HaRakhamim as enumerated in the Book of Exodus are the Divine Attributes with which, according to Judaism, God governs the world. According to the explanation of Maimonides these attributes must not be regarded as qualities inherent in God, but as the method of His activity, by which the divine governance appears to the human observer to be controlled. In the Sifre, however, these attributes are not called "middot", which may mean "quality" as well as "rule" and "measure", but "derakhim", since they are the ways of God which Moses prayed to know and which God proclaimed to him. The thirteen attributes are alluded to a number of other times in the Bible. Verses where God is described using all or some of the attributes include,,,,,,,, and.
Division
The number thirteen is adopted from Talmudic and rabbinic tradition. There are divergent opinions as to which word they begin and with which they conclude. According to some, the Thirteen Attributes begin with the first "Adonai", in verse 6, and end with the word "ve-nakeh" in verse 7. The single attributes are contained in the verses as follows:
יְהוָה YHVH: compassion before a person sins;
יְהוָה YHVH: compassion after a person has sinned;
אֵל El: mighty in compassion to give all creatures according to their need;
רַחוּם Raḥum: merciful, that humankind may not be distressed;
וְחַנּוּן VeḤanun: and gracious if humankind is already in distress;
According to others, the Thirteen Attributes begin only with the second "Adonai", since the first one is the subject of vayikra. In this case, to achieve the total of thirteen attributes, some count notzer hesed la-alafim as two while others divide erekh appayim into two, since forbearance is shown both to the good and to the wicked, and still others end the thirteenth middah with "lo yenakeh", this being considered a good quality, since through punishment man is moved to repentance, after which he is pardoned and pure. Others term "ve-nakeh lo yenakeh" a single middah, the thirteenth being, in their opinion, "poked avon avot al banim", "this being regarded as compassionate since the transgressor is not punished immediately".
Liturgical usage
The general usage is that the various recitations of the thirteen middot begin with the first "Adonai" and conclude with "ve-nakeh". They must not be recited by only one person in prayer, but by an entire congregation, which must consist of at least ten persons, a minyan.
In Ashkenazi synagogues, it is also customary that on the fast days on which Exodus 32:11–14 and 34:1–10 are read, the reader stops at the word "Vayikra" in order that the congregation may recite the thirteen attributes, after which he continues his reading.
The Thirteen Attributes are very frequently recited in Selichot prayers, as in the case in the seliḥah of the eve of Rosh Hashanah, which is repeated at the morning service on Yom Kippur, and which begins with the words "Shelosh esreh middot", and in the pizmonEzkera Elohim of Amittai b. Shephatiah for the fifth day of repentance, which is recited also at the evening service on Yom Kippur, and in which the attribute of compassion is particularly invoked.
On fast-days as well as during the week before the New Year, and on the days between the New Year and the Day of Atonement, called the days of repentance, many penitential prayers are recited in addition to the usual daily prayers. After every such petition the thirteen middot are recited with their introductory prayer, the well-known El Meleḥ yoshev, which runs as follows: "Almighty King, sittest on the throne of mercy, showing forth Thy compassion, and forgiving the sins of Thy people by ever taking away their former guilt, ofttimes granting pardon unto sinners and forgiveness to the transgressors, making manifest Thy goodness both to body and to soul, nor punishing them according to their iniquity; Almighty One, as Thou hast taught us to recite the thirteen , so remember now the thirteenfold covenant, as Thou didst in former days proclaim it to the modest one , even as it is written...".
