Memunim are elemental beings mentioned in Jewish mythology and magickal texts. Sometimes they are considered a class of angels.
Each is appointed to watch over a very specific aspect of air, land, water, time, and place, such as a blade of grass.
In my telling, each memuneh (singular), carries a small scroll tucked in their apron that holds their sacred assignment. On the outside, you will see the category of their care, but what is on the inside is just for them.
MEMUNEH: Originally this referred to the deputy High Priest. It came to refer to the genius or angel that energizes every discrete phenomenon in the universe. Thus every star, planet, month, day, human, nation, land, and even abstractions like “justice” and “love,” have their own memuneh. Barely mentioned in rabbinic literature, it becomes more prominent in the Middle Ages.

Please, God, who makes, forms, creates, and emanates supernal worlds and created their likeness on the earth below, according to their supernal form and character. “All of them You made with wisdom,”supernal [forms] above and lower [forms] below, to join together the tent so as to be one. You caused trees and grass to grow from the earth, according to the structure and character of [the forms] above, so that human beings might gain wisdom and understanding through them, and thus grasp the hidden [forms]. You appointed your holy angels over them as agents to oversee their growing. And you caused shefa and the power of your supernal qualities to flow upon them.
יְהֹוָה אֱלֹהַי אַתָּה אֲרוֹמִמְךָ אוֹדֶה שִׁמְךָ כִּי עָשִׂיתָ פֶּלֶא עֵצוֹת מֵרָחוֹק אֱמוּנָה אֹמֶן,
Every word that issues forth from God’s mouth is divided into a number of sparks, and an angel is created in accordance with every spark. Each angel is in charge of something, such as a tree or a blade of grass. The angel’s ability to receive vitality from God’s speech — the Torah — and give to the entity that it influences is called its “hands.”
Since the Torah gives power to the angels, and they in turn influence grasses and herbs which are made into healing medicines, all medicines ultimately depend on the Torah. If a person lacks faith in the Torah sages and ignores their rulings, he removes the “hands” from the angels. As a result, he suffers from illness that cannot be cured. Only when he raises up his fallen faith can he be healed.
He raises up his fallen faith by making vows. This elevates him to the spiritual level that is the source of the sages, and then he can appreciate and believe in them. This leads to an elevation of the spiritual pleasure of the Shabbat, which is expressed in eating in holiness.
When a person eats on the weekdays, the Other Side derives some benefit from it. But when he eats on the Shabbat, the Other Side derives no benefit. His Shabbat eating is completely holy and Godly. Therefore, on the Shabbat, a person can accomplish with his eating what he could accomplish on a weekday only with fasting — and that is the downfall of his enemies. Why is that?
Anger is associated with the liver — which, during the weekdays, takes precedence over the brain. When a person is angry, he can be attacked by enemies, since they do not fear him. Human beings are feared only because of the image of God that they possess. When they no longer possess that image, they become animalistic. When a person grows angry, the image of God leaves him, and thus he is not feared. But when a person fasts and does not feed his liver, he restores his Godly image. Then his enemies fall before him. A person who attains the delight of the Shabbat, however, has no need to fast. Indeed, the peace attained by the delight of the Shabbat is superior to the peace attained through a weekday fast. And superior to both is a level called “a profusion of peace,” which a person attains by giving charity generously. “One who increases charity increases peace.”
“HaShem, You are my God; I will exalt You. I will give thanks to Your Name because You have sent wonders, counsel from the earliest times. Your faithfulness has been established.”
