The Choirs (a field guide)המחנות

One choir per sephirah, per Maimonides' and the kabbalists' rosters (they differ; the app follows the kabbalistic one): Chayot ha-Kodesh (Keter) who bear the Throne; Ophanim (Chokhmah), Ezekiel's wheels awake with eyes; Aralim (Binah), thrones of endurance; Chashmalim (Chesed), the speaking-silence amber beings; Seraphim (Gevurah), the burners of Isaiah 6; Malachim (Tiferet), the plain messengers; Elohim (Netzach); Bene Elohim (Hod); Cherubim (Yesod) — not putti: sword-bearing hybrid guardians; Ishim (Malkhut), the "persons," nearest to us, possibly us on good days.
