Ezekiel 33:6-8

Thomson(i) 6 But if the watchman, upon seeing the sword coming, doth not sound the trumpet, and the people are not warned, and the sword cometh and taketh the life of any of them; that person is taken off because of his iniquity; but his blood I will require at the watchman's hands. 7 Now, as for thee son of man, I have made thee a watchman to the house of Israel, therefore thou shalt hear a word from my mouth. 8 When I say to the sinner, Thou shalt die: if thou dost not speak to warn the wicked from his way; that unrighteous man shall die for his iniquity; but his blood I will require at thy hand.
