וַיֹּאמֶר֩ ע֨וֹד אֱלֹהִ֜ים אֶל־מֹשֶׁ֗ה כֹּֽה־תֹאמַר֮ אֶל־בְּנֵ֣י יִשְׂרָאֵל֒ יְהוָ֞ה אֱלֹהֵ֣י אֲבֹתֵיכֶ֗ם אֱלֹהֵ֨י אַבְרָהָ֜ם אֱלֹהֵ֥י יִצְחָ֛ק וֵאלֹהֵ֥י יַעֲקֹ֖ב שְׁלָחַ֣נִי אֲלֵיכֶ֑ם זֶה־שְּׁמִ֣י לְעֹלָ֔ם וְזֶ֥ה זִכְרִ֖י לְדֹ֥ר דֹּֽר׃
און גאָט האָט װײַטער געזאָגט צו משהן: אַזױ זאָלסטו זאָגן צו די קינדער פֿון ישׂראל: ה׳, דער גאָט פֿון אײַערע עלטערן, דער גאָט פֿון אַבֿרהמען, דער גאָט פֿון יצחקן, און דער גאָט פֿון יעקבֿן, האָט מיך געשיקט צו אײַך. דאָס איז מײַן נאָמען אױף אײביק, און דאָס איז מײַן געדעכעניש אױף דוֹר-דוֹרות.
Mishneh Torah, Prayer and the Priestly Blessing
The name of God was pronounced as written; that is, the name of which the utterance is according to the letters Yod, He, Vav, He. This is the Ineffable Name (literally the Proper Name), wherever it is referred to. Outside the temple the usual pronunciation is used, as if it were written A.D.N.I.*Adonai—my Lord.; for the Proper Name of God as written, is pronounced nowhere but in the Temple. After the death of Simon the Just, the priests ceased to utter the proper name of God in the Benediction, even in the Temple, so that an unworthy or unsuitable person should not learn it. The ancient teachers did not teach this name to their disciples or sons, even when they were worthy, except once in seven years—all this out of respect to the Honored and Revered Name of God.
