Berit Menuchah (Hebrew: ספר ברית מנוחה) (also Berit Menuḥah, Berith Menuḥa, or Brit Menucha) is a practical kabbalistic work written in the 14th century, by Rabbi Abraham ben Isaac of Granada. It consists of a system of theurgy which uses secret names of G–d and his emanations for spiritual and magical purposes. An English translation thereof was published in 2007.
The Berit Menuḥah focuses on a complex system describing the various hypostases of the divine world and G–d, and associating them with the vowel points (Nikudim) of the Hebrew language. Especially central is the role of divine, angelic, and magical names associated with the various emanations described. They are often given magical uses, and the text often specifies whether the practitioner needs to be pure or not in order to use them. Some of the names are typical Kabbalistic names of G–d, but the majority are derived by Notarikon from biblical verses:
And it was discovered that the Malachim were created from the wind and the fine and enlightening air, and that the name of their origin עַמַרֻמְאֵליוְהָ was derived from the verse (Psalms 104:4): ‘Who makest the winds thy messengers, fire and flame thy ministers’ (.....) And when the lights reach this Sefira, they unite and receive a name that is derived from the central letters of the following verse (Genesis 6:2): ‘The sons of G–d saw that the daughters of men were fair; and they took to wife such of them as they chose.’ And this valiant name, which is drawn in the Gevura, is רְנֵלבֺנקְהֵכשְיִהְ
Angels and their names also feature prominently in the text, and one section lists dozens of them and their areas of dominion, such as animals, trees, elements, etc.:
The angel רוחיאל (Rohiel) is in charge of the winds; he is the captain of three angels: חזקיה , עוזיאל and עזאל (Uziel, Hezekiah and Azael). The angel גבריאל (Gabriel) is in charge of the thunders. The angel נוריאל (Nuriel) is in charge of the hailstones. The angel מקטוניאל (Mktoniel?) is in charge of the rocks. The angel טלפיאל (Tlapial?) is in charge of the trees that bear fruits. The prince שרואל (Ruel) is in charge of the fruitless trees. And the angel סנדלפון is in charge of human beings.
*Because of an ad appearing in the Mishpacha Magazine, and a retort concerning this ad, I found the subject-matter very interesting. Therefore I present here Wikipedia’s explanation of Brit Menucha.

**A 14th century kabbalah book which deals with names of angels and their role in the universe. This profound kabbalistic work was acclaimed by R' Moshe Cordevero to be the product of Divine Inspiration, for no one could perceive such hidden secrets by intellect alone. The Ari called it a penetrating and completely reliable kabbalistic source, revealed to the author by Eliyahu the Prophet. There is an introduction in this book by Machon Ramchal, analyzing the influence of 'Brit Menucha' on the Ramchal.
