Ezekiel 33:2-6

2“Son of man, speak to your people and say to them: ‘When I bring the sword against a land, and the people of the land choose one of their men and make him their watchman, 3and he sees the sword coming against the land and blows the trumpet to warn the people, 4then if anyone hears the trumpet but does not heed the warning and the sword comes and takes their life, their blood will be on their own head. 5Since they heard the sound of the trumpet but did not heed the warning, their blood will be on their own head. If they had heeded the warning, they would have saved themselves. 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.’
