"To every minister the Lord declares: “O son of man, I have set thee a watchman unto the house of Israel; therefore thou shalt hear the word at My mouth, and warn them from Me. When I say unto the wicked, O wicked man, thou shalt surely die; if thou dost not speak to warn the wicked from his way, that wicked man shall die in his iniquity; but his blood will I require at thine hand. Nevertheless, if thou warn the wicked of his way to turn from it, ... thou hast delivered thy soul.” Ezekiel 33:7-9 . AA 360.4"
"So thou, O son of man, I have set thee a watchman unto the house of Israel; therefore thou shalt hear the word at my mouth, and warn them from me. When I say unto the wicked, O wicked man, thou shalt surely die; if thou dost not speak to warn the wicked from his way, that wicked man shall die in his iniquity; but his blood will I require at thine hand. Nevertheless, if thou warn the wicked of his way to turn from it; if he do not turn from his way, he shall die in his iniquity; but thou hast delivered thy soul."
