וָאֵרָ֗א אֶל־אַבְרָהָ֛ם אֶל־יִצְחָ֥ק וְאֶֽל־יַעֲקֹ֖ב בְּאֵ֣ל שַׁדָּ֑י וּשְׁמִ֣י יְהוָ֔ה לֹ֥א נוֹדַ֖עְתִּי לָהֶֽם׃
Ich bin auch Abraham, Isaak und Jakob erschienen mit [dem Namen]: Gott, Allmächtiger; aber mit meinem Namen Adonai, bin ich ihnen nicht kund geworden.
On the Change of Names
[13] For those who are born into mortality must needs have some substitute for the divine name, so that they may approach if not the fact at least the name of supreme excellence and be brought into relation with it. And this is shown by the oracle proclaimed as from the mouth of the Ruler of all in which He says that no proper name of Him has been revealed to any. “I was seen,” He says, “of Abraham, Isaac and Jacob, being their God, and My name of’ ‘Lord’ I did not reveal to them” (Ex. 6:3). For when the transposition is reset in the proper order it will run thus, “My proper name I did not reveal to thee,” but, He implies, only the substitute, and that for reasons already mentioned.
