Ezekiel 33:7-8

⁷So you, son of man, I have set you a watchman to the house of Israel; therefore hear the word at my mouth, and give them warning from me. ⁸When I tell the wicked, O wicked man, you shall surely die, and you don`t speak to warn the wicked from his way; that wicked man shall die in his iniquity, but his blood will I require at your hand.
