Ezekiel 33:2-5

2‘Son of man, speak to your people. Say to them, “Think about what might happen if I send an army to attack a country. The people of that country might choose one of their own men to be a guard to warn them about danger.

3Then, if the guard sees that enemy soldiers are ready to attack, he must blow a trumpet to warn his people.

4Someone might hear the sound of the trumpet, but he does nothing to keep himself safe. If enemy soldiers then come and kill that person, he is guilty of his own death.

5He deserves to die because he heard the sound of the trumpet, but he did nothing. When the trumpet warned him of danger, he should have got ready. If he had done that, he would have saved his life.
