Ezekiel 33:8-9
When I say to the wicked,
'O wicked man,
you will surely die,'
and you do not speak out to dissuade him from his ways,
that wickedman will die for his sin
and I will hold you accountable for his blood.
But if you do warn the wicked man to turn from his ways
and he does not do so,
he will die for his sin,
but you will have saved yourself.
- Ezekiel 33:8-9 (NIV)
