U

Ubuntu

Ubuntu is a Nguni Bantu term translated as “humanity towards others.” A broader understanding of the term would be “the belief in a universal bond of sharing that connects all humanity,” (https://en.wikipedia.org/wiki/Ubuntu_philosophy). In Mormon Kabalistic ideology it’s Zion: “I am because we are.” 
We all share the same creator, and are all the children of God, as we learn in the first book of Genesis. This bond is universal and connects all of us. The greater we understand this principle, as taught in Kabbalah, the greater we understand ubuntu and our creator.

Unclean

Hebrew, (טמא), “tame.” In both the Torah of Judea (Judah, Benjamin, and Levi) and in the Torah of Lehi (Joseph), some animals are explicitly named as pure or impure, while others are classified by other criteria. Unclean animals can range from weak, sickly, or sick animals to animals sacrificed, made for, or given to foreign gods. 
In Judaism the concept of “impure animals” plays a prominent role in dietary requirements as a part of Jewish law that specifies which foods are allowed (kosher) or forbidden to eat. These laws are based upon the Books of Leviticus and Deuteronomy of the Torah (the Christian Old Testament). 
Rabbinical commentaries like the Talmud have added to these laws over time to help the Jewish people better obey the commandments of God as they understand them. 
The Hebrew term “tame,” or in English “unclean,” typically refers to anything that can make people sick, mostly physically but sometimes spiritually. This idea seems to be more of a temporal health code than spiritual law, similar to the Word of Wisdom. 
See 5 Moses 8:17, & chapter 11; Leviticus 11; Deuteronomy 12:15, & chapter 14; Matthew 15:10-11; Mark 7:1-5, 14-19; Acts 10:9- 16.

Urim and Thummim

Hebrew, “Lights and Perfections.” A holy or sacred device for divination, cleromancy, and divining oracles. They were used by the High Priest and High Priestesses to answer a question or reveal the will of God. Some scholars believe that this refers to two objects used to answer yes or no questions. 
The meaning of these terms is uncertain, possibly Urim from the root word “Lights” and Thummim from the root “Innocents,” generally taken to mean “Perfections.” The terms together may also mean “revelation and truth.” The Urim and Thummim are mentioned in the Hebrew Bible as a part of the breastplate worn by the High Priest. In the plates of brass, they are also worn by the High Priestesses. They were believed to be used for divination and cleromancy. 
The urim and thummim of Abraham and of the Nephites may not be the same type of urim and thummim used by the Levite Priests and Priestesses. The Urim and Thummim used to divine the translation of the lost 116 pages of Book of Lehi were not identical to the Urim and Thummim of the Old Testament. According to page 101 of Lucy Mack Smith, mother or Joseph Smith Jr.’s 1853 “Biographical sketches of Joseph Smith the prophet, and his progenitors for many generations” they were “two smooth three-cornered diamonds.” These “diamonds” were said to have been placed in silver bows that were fastened to a breastplate. 
In the Latter Day Saint movement, Urim and Thummim may also refer to a seer stone, something similar to the rock Joseph Smith Jr. placed in a hat to translate the Book of Mormon. The “Urim and Thummim” actually used to divine the translation of the Book of Mormon available to readers today was given to Joseph Smith Jr. by placing his brown seer stone into a hat. This is clearly different from the bow attaching glasses to a chest plate kept with the gold plates and what is described in the Old Testament and the plates of brass.
