“But if the watchman see the sword come, and blow not the trumpet, and the people be not warned; if the sword come, and take [any] person from among them, he is taken away in his iniquity; but his blood will I require at the watchman’s hand.
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.” Ezekiel 33:6-7 (KJV)
