Ezekiel 33
7 Ref So thou, son of man, I have set thee a watchman unto the house of Israel; therefore hear the word at my mouth, and give them warning from me.
8 Ref When I say unto the wicked, O wicked man, thou shalt surely die, and 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 thy hand.
