In Jewish tradition

In the Torah, the word is just the English "united," meaning joined; Jacob asks that his glory not be joined to the assembly of Simeon and Levi. In Sefer Yetzirah, the "Uniting Intelligence" is one of the paths of wisdom.

Interpretation. Jacob's words in Genesis 49:6 are read as a curse on the violent anger of Simeon and Levi. In the Kabbalah, the "paths" of the Sefirot are ways that God's power joins the world together.

Examples

• Let my soul not come into their council; unto their assembly let my glory not be united; for in their anger they slew men, and in their self-will they houghed oxen. (Torah GEN.49.6, JPS 1917) tree →
• This text is in the public domain in the United States because it was published prior to January 1st, 1923. (Sefer Yetzirah, Kalisch 1877) tree →
• The Thirteenth Path is named the Uniting Intelligence and is so called because it is itself the essence of Glory. (Sefer Yetzirah, Westcott 1887) tree →
