It might be shocking, but true..
and based on studies im Jewish Mysticism !
The Name is: Rabbi Judah..
the time: 12 century AD
but let's get to the story:It is significant that the same 19-based mathematical composition was discovered by Rabbi Judah in the 12th century AD in a preserved part of the Old Testament. Below is a quote from Studies In Jewish Mysticism.
"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 were 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 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 (blessed are those 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, 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 . . ."
