So "all" doesn't always mean "all" in the Bible. Exodus 9:6 So all the
livestock of Egypt died, the fifth plague. Sixth plague vs 10 "And
they caused boils on men and beast".
Poor beast or livestock, what the hell did they do. They always get
the short end of the stick, just grazing in the pasture and zap boils.
What does God have against animals.
