Note 5 — I.
Reading edition
Both the etymology and the exact meaning of the word ספירה (plural ספירות) are matters of dispute. R. Azariel, the first Kabbalist, derives it from ספר to number, whilst the later Kabbalists derive it alternately from ספיר Saphir, from השמים מספרים כבוד אל ( Ps. xix, 1 ), and from the Greek σφαῖραι, and are not at all certain whether to regard the Sephiroth as principles (ἀρχαὶ), or as substances (ὑποστάσεις), or as potencies, powers (δυνάμεις), or as intelligent worlds (κόσμοι νοητικοί), or as attributes, or as entities (עצמות), or as organs of the Deity (כלים). ↑
