Ezekiel 33:6-7

6But if the watchman sees the sword coming and does not blow the trumpet to warn the people and the sword comes and takes someone’s life, that person’s life will be taken because of their sin, but I will hold the watchman accountable for their blood.’ 7“Son of man, I have made you a watchman for the people of Israel; so hear the word I speak and give them warning from me.
