And at the end of seven days, the word of the LORD came to me: “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.
–Ezekiel 3:16-19
