Taurus - Tau

Taurus - Tau
 The final character on the lower left is not connected with any Hebrew letter. The editors of The Dead Sea Scrolls Uncovered speculate that it was used as a null character, merely to confuse those attempting to decipher the coded text. If this magic alphabet were to be employed in modern magic, this extra character would be put to best use by making it stand for a period at the end of sentences.
Another explanation is that the final letter represents Taurus, such that the final 2 letters Tau -Taurus represent the NW - SE  axis. Reversed
Taurus = Bull with all its energy and force in Taurus
Tau      =  represents the return to energy at the border of Scorpio/Sagittarius
