And how do we know this of murder itself? —
It is common sense.
As the one who came before Raba and said to him,
'The governor of my town has ordered me:
"Go and kill so and so; if not, I will slay thee"'.
Raba answered him, :
'Let him rather slay you
than that you should commit murder;
for who knows if your blood is redder?
Perhaps his blood is redder.'
