Subject: Inside AV engines?

from another.

"O  caminho  do  homem  de  bem  ?  cercado de
todos os lados  pelas  iniq?idades do  ego?smo
e tirania  dos homens maus.  Aben?oados os que,
em  nome da caridade e  boa vontade,  conduzem
os  fracos pelo  vale das  sombras, pois ele ?
o  guardi?o  de seu irm?o e o  que encontra os
filhos perdidos. E eu vou  atacar com vingan?a
e f?ria  os que tentarem  envenenar e destruir
meus irm?os. E quando minha vingan?a se abater
sobre  eles,  saber?o  que  eu sou  o Senhor."

(Ezequiel, 25, 17)
