At the time of the Temple, the Big Kohen (the High Priest) used to bless the Jewish people twice a day. 
The Priestly blessing is featured on this print as a code. The coded blessing is in Hebrew and therefore it’s to be read from top right to left.
 
The first 9 letters are represented with circles
And so forth until the ninth letter Tet .

The tenth letter is Yod = 10, for the next 9 letters we change the symbol to
