Shekhinah, from a root meaning to dwell, names God's indwelling presence. The noun itself is rabbinic rather than biblical, but it gathers up biblical language: the glory that fills the tabernacle so that Moses cannot enter (Exodus 40:34-35) and the Temple so that the priests cannot stand to minister (1 Kings 8:10-11), and the promise "I will dwell among the children of Israel and be their God" (Exodus 29:45).
Rabbinic literature uses the term to speak of where God's presence rests and where it withdraws. It rests where ten gather for prayer, where judges judge honestly, where a person sits and studies Torah, and between a husband and wife at peace; it departs where there is bloodshed, idolatry or slander. Its most consequential development is the teaching that the Shekhinah accompanies Israel into exile and will return with them, "wherever they were exiled, the Shekhinah went with them" (Megillah 29a), which makes the divine presence a fellow-sufferer rather than a spectator of history.
In Kabbalah the term shifts decisively. Shekhinah becomes the tenth and lowest sefirah, Malkhut, and is consistently figured in feminine terms: the daughter, the bride, the Community of Israel, the moon that has no light of its own but receives. The exile of the Shekhinah is now the separation of this sefirah from the sixth, Tiferet, and the purpose of religious action becomes their reunion, stated directly in the Lurianic and Hasidic formula recited before performing a commandment, "for the sake of the union of the Holy One, blessed be He, and his Shekhinah."
That feminine figuration is contested in current discussion. Jewish feminist theologians have taken up the Shekhinah as a feminine image of the divine already present in the tradition's own vocabulary rather than imported into it. Others have cautioned that the kabbalistic Shekhinah is receptive, dependent and lowest in a hierarchical scheme, so that recovering it uncritically may carry the hierarchy along with it. Historians add a further caution: rabbinic usage looks in most cases like a way of speaking about God's presence rather than a distinct entity, and reading the later kabbalistic content back into the rabbinic texts is anachronistic.
