Ezekiel 33, 1.7-9
The word of Yahweh was addressed to me as follows,
'Son of man I have appointed you as watchman for the House of Israel. When you hear a word from my mouth, warn them from me.
If I say to someone wicked, "Evil- doer, you are to die," and you do not speak to warn the wicked person to renounce such ways, the wicked person will die for this guilt, but I shall hold you responsible for the death.
If, however, you do warn someone wicked to renounce such ways and repent, and that person does not repent, then the culprit will die for this guilt, but you yourself will have saved your life.
