Forty-Two Letter Name
I want to ask for an explanation about the source of the letters ABG YTZ etc. in the 42 letters that start the 42 words of the ANA BEKOACH we recite in the Korbanot following Birkot HaShachar.
I know about the Holy Name of 42, being derived from the letters of Havayah, their Milui and the milui of the milui, but I don’t know at all what is the source, origin, of the letters ABG YTZ etc. used in ANA BEKOACH.
Please explain to me,
Thank you in adavance,
