Rational persons ought not to listen to such men, nor in any way believe their assertions. No other name is called shem ha-meforash except this Tetragrammaton, which is written, but is not pronounced according to its letters. The words, “Thus shall ye bless the children of Israel” (Num. vi. 23) are interpreted in Siphri as follows: “‘Thus,’ in the holy language; again ‘thus,’ with the Shem ha-meforash.” The following remark is also found there: “In the sanctuary [the name of God is pronounced] as it is spelt, but elsewhere by its substitutes.” In the Talmud, the following passage occurs: “‘Thus,’ i.e., with the shem ha-meforash.—You say [that the priests, when blessing the people, had to pronounce] the shem ha-meforash; this was perhaps not the case, and they may have used other names instead.—We infer it from the words: ‘And they shall put My name’ (Num. vi. 27), i.e., My name, which is peculiar to Me.” It has thus been shown that the shem ha-meforash (the proper name of God) is the Tetragrammaton, and that this is the only name which indicates nothing but His essence, and therefore our Sages in referring to this sacred term said “‘My name’ means the one which is peculiar to Me alone.” In the next chapter I will explain the circumstances which brought men to a belief in the power of Shemot (names of God); I will point out the main subject of discussion, and lay open to you its mystery, and then not any doubt will be left in your mind, unless you prefer to be misguided. CHAPTER LXII We were commanded that, in the sacerdotal blessing, the name of the Lord should be pronounced as it is written in the form of the Tetragrammaton, the shem ha-meforash. It was not known to every one how the name was to be pronounced, what vowels were to be given to each consonant, and whether some of the letters capable of reduplication should receive a dagesh. Wise men successively transmitted the pronunciation of the name; it occurred only once in seven years that the pronunciation was communicated to a distinguished disciple. I must, however, add that the statement, “The wise men communicated the Tetragrammaton to their children and their disciples once in seven years,” does not only refer to the pronunciation but also to its meaning, because of which the Tetragrammaton was made a nomen proprium of God, and which includes certain metaphysical principles.
