This design incorporates Star of David with the Ana Becoach prayer. Both Concepts are made for protection.
The Ana Becoach prayer was written in the first century by a great kabbalistic Rabbi - Rabbi Nehonia. The prayer was written according to the seventy names of God - a term related to Abraham. The Ana Becoach is composed of seven lines, with six words in each line. The first letter of every word is taken, thereby creating the 42-letter name.
The combination of Ana Becoach is hidden in the first 42 letters of the book of Genesis (From the word BERESHIT to the word VAVOHOO). The letters are translated using a secret kabbalistic calculation.
Kabbalists use the Ana Becoach prayer for protection, healing, and balancing.
