"Son of man, I have made you a watchman for the house of Israel; whenever you hear a word from my mouth, you shall give them warning from me. If I say to the wicked, 'You shall surely die,' and you give him no warning, nor speak to warn the wicked from his wicked way, in order to save his life, that wicked man shall die in his iniquity; but his blood I will require at your hand. But if you warn the wicked, and he does not turn from his wickedness, or from his wicked way, he shall die in his iniquity; but you will have saved your life. Again, if a righteous man turns from his righteousness and commits iniquity, and I lay a stumbling block before him, he shall die; because you have not warned him, he shall die for his sin, and his righteous deeds which he has done shall not be remembered; but his blood I will require at your hand. Nevertheless if you warn the righteous man not to sin, and he does not sin, he shall surely live, because he took warning; and you will have saved your life."
Ezekiel 3:17-21 RSV-CE
