I Am Hashem Elohei Avoteichem, Elohei Avra'ham, Yitzchak, and Ya'akov. There is no other Elohim besides Me: El Tzaddik and Moshi’a; there is none besides Me.
Turn unto Me, and be ye saved, kol afsei Eretz (all the ends of the Earth); I am El (G-d), and there is no other [G-d]. And I will bring you in unto HaAretz, concerning the which I did lift up My hand to swear to give it to Avraham, to Yitzchak, and to Ya’akov; and I will give it to you for a morashah (heritage); I am Hashem.
The Meaning of Seventy - שבעים speaks of an elevated connection, of building a community.
