An ancient saying sheds light on this matter: “There is one (εἷς ἐστ’ Deuteronomy 6:4) who is complete in himself, but all things are completed by him, and he himself moves about in them.” Aristobulus uses the Greek phrase of the Septuagint (εἷς ἐστ’) to make this statement. (Eusebius, Praeparatio Evangelica 13.12.5) See Carl R. Holladay, Fragments from Hellenistic Jewish Authors, vol. 3: Aristobulus (Atlanta: Scholars Press, 1995), pp. 166–167.
