In Judaism, God has been conceived in a variety of ways. Traditionally, Judaism holds that God—that is, the god of Abraham, Isaac and Jacob, and the national god of the Israelites—delivered them from slavery in Egypt, and gave them the Law of Moses at Mount Sinai as described in the Torah. Jews believe in a monotheistic conception of God ("God is one"), characterized by both transcendence (independence from, and separation from, the material universe) and immanence (active involvement in the material universe).
God is seen as unique and perfect, free from all faults, and is believed to be omnipotent, omnipresent, omniscient, and unlimited in all attributes, with no partner or equal, serving as the sole creator of everything in existence. In Judaism, God is never portrayed in any image. The names of God used most often in the Hebrew Bible are the un-pronounced Tetragrammaton (Hebrew: יהוה, romanized: YHWH) and Elohim. Other names used to refer to God in traditional Judaism include Adonai, El-Elyon, El Shaddai, and Shekhinah.
