ייִדישער מחשבֿה אויף בראשית 18:3

This important principle was adopted by one of our Sages, one of the most distinguished among them, R. Ḥiya the Great (Bereshit Rabba, xlviii.), in the exposition of the Scriptural passage commencing, “And the Lord appeared unto him in the plain of Mamre” (Gen. xviii.). The general statement that the Lord appeared to Abraham is followed by the description in what manner that appearance of the Lord took place; namely, Abraham saw first three men; he ran and spoke to them. R. Hiya, the author of the explanation, holds that the words of Abraham, “My Lord, if now I have found grace in thy sight, do not, I pray thee, pass from thy servant,” were spoken by him in a prophetic vision to one of the men; for he says that Abraham addressed these words to the chief of these men. Note this well, for it is one of the great mysteries [of the Law].

IT is well known that all the names of God occurring in Scripture are derived from His actions, except one, namely, the Tetragrammaton, which consists of the letters yod, hé, vau and hé. This name is applied exclusively to God, and is on that account called Shem ha-meforash, “The nomen proprium.” It is the distinct and exclusive designation of the Divine Being; whilst His other names are common nouns, and are derived from actions, to which some of our own are similar, as we have already explained. Even the name Adonay, “Lord,” which has been substituted for the Tetragrammaton, is derived from the appellative “lord”; comp. “The man who is the lord (adone) of the land spake roughly to us” (Gen. 43:30). The difference between Adoni, “my lord,” (with ḥirek under the nun), or Adonay (with kameẓ), is similar to the difference between Sari, “my prince,” and Saraï, Abraham’s wife (ib. 16:1), the latter form denoting majesty and distinction. An angel is also addressed as “Adonay”; e.g., “Adonay (My lord), pass not away, I pray thee” (ib. 18:3). I have restricted my explanation to the term Adonay, the substitute for the Tetragrammaton, because it is more commonly applied to God than any of the other names which are in frequent use, like dayyan, “judge,” shadday, “almighty,” ẓaddik, “righteous,” ḥannun, “gracious,” raḥum, “merciful,” and elohim “chief” all these terms are unquestionably appellations and derivatives. The derivation of the name, consisting of yod, hé, vau, and hé, is not positively known, the word having no additional signification. This sacred name, which, as you know, was not pronounced except in the sanctuary by the appointed priests, when they gave the sacerdotal blessing, and by the high priest on the Day of Atonement, undoubtedly denotes something which is peculiar to God, and is not found in any other being. It is possible that in the Hebrew language, of which we have now but a slight knowledge, the Tetragrammaton, in the way it was pronounced, conveyed the meaning of “absolute existence.” In short, the majesty of the name and the great dread of uttering it, are connected with the fact that it denotes God Himself, without including in its meaning any names of the things created by Him. Thus our Sages say: “‘My name’ (Num. 6:27) means the name which is peculiar to Me.”
