...the words and letters of the various prayers are not accidental, nor are they only vehicles for their literal meaning. Their order, especially their numbers, reflect a mystical harmony, a sacred divine rhythm. This mystical harmony can be discovered in historical events, directed by God; in nature, especially in the miraculous occurrences directly influenced by divine powers; and first and foremost, in the Bible. According to Rabbi Judah and the Ashkenazi Hasidic school in general, there can be nothing accidental in the Bible, not even the forms of letters, the punctuation, the vocalization, and especially-in the numerical structures-the number of certain letters, consonants or vowels in a certain verse; the number of words from the same root; the number and variety of divine names in a certain pericope, the absence of one or more letters from a chapter, and many other elements of the Scriptures besides their content.
Nine centuries after Rabbi Judah stated these elements of the code, the computer has demonstrated each of them. As detailed in this chapter and the next, the original scripture was mathematically composed in a way that encodes and guards every single one of its parameters. If the scripture were tampered with, the code would be broken.
Joseph Dan writes that Rabbi Judah was critical of the French and British Jews when they altered the morning prayer by adding a few words (Ibid., p. 88). Rabbi Judah pointed out that such an addition destroys the numerical structure of the prayer and renders it utterly nullified. He maintained that it is the "numerical combination," rather than the "meanings" of the words that effects the needed contact between the worshiper and God. Even the specific, nineteen-based, numerical system of the scripture was reported by Rabbi Judah:
The people [Jews] in France made it a custom to add [in the morning prayer] the words: " 'Ashrei temimei derekh [blessed are those who walk the righteous way]," and our Rabbi, the Pious, of blessed memory, wrote that they were completely and utterly wrong. It is all gross falsehood, because there are only nineteen times that the Holy Name is mentioned [in that portion of the morning prayer] ...and similarly you find the word 'Elohim nineteen times in the pericope of Ve-'elleh shemot.... Similarly, you find that Israel is called "sons" nineteen times, and there are many other examples. All these sets of nineteen are intricately intertwined, and they contain many secrets and esoteric meanings, which are contained in more than eight large volumes. Therefore, anyone who has the fear of God in him will not listen to the words of the Frenchmen who add the verse "'Ashrei temimei derekh," and blessed are the righteous who walk in the paths of God's Torah, for according to their additions the Holy Name is mentioned twenty times...and this is a great mistake.
Furthermore, in this section there are 152 words (152 = 19 x 8) but if you add "'Ashrei temimei derekh" there are 158 words. This is nonsense, for it is a great and hidden secret why there should be 152 words...but it cannot be explained in a short treatise. ...In order to understand this religious phenomenon, we have to take the basic contention of this treatise exactly as it is stated: every addition or omission of a word, or even of a single letter, from the sacred text of the prayers destroys the religious meaning of the prayer as a whole and is to be regarded as a grave sin, a sin which could result in eternal exile for those who commit it....
