In Judaism, the Holy Spirit (, ruach ha-kodesh) refers to the divine force, quality, and influence of God over the universe or over God's creatures, in given contexts. Hebrew Bible "Holy Spirit" The term "holy spirit" appears three times in the Hebrew Bible: Psalm 51 refers to "Your holy spirit" (ruach kodshecha) and Isaiah refers twice to "His holy spirit" (ruach kodsho).

The rabbinical understanding of the Holy Spirit has a certain degree of personification, but it remains, "a quality belonging to God, one of his attributes". The idea of God as a duality or trinity is considered shituf (or "not purely monotheistic"). Nature What the Bible generally calls "Spirit of God" is called in the Talmud and Midrash "Holy Spirit" due to the disinclination to the use of the Tetragrammaton. It is probably owing to this fact that the Shekhinah is often referred to instead of the Holy Spirit. It is said of the former, as of the Holy Spirit, that it rests upon a person. The difference between the two in such cases has not yet been determined. Although the Holy Spirit is often named instead of God, it was conceived as being something distinct. The Spirit was among
