Ezekiel 33:2-5

2“Son of man, speak to your people and tell them, ‘Suppose I bring the sword against a land, and the people of that land select a man from among them, appointing him as their watchman.

3And suppose he sees the sword coming against the land and blows his ram’s horn to warn the people.

4Then, if anyone hears the sound of the ram’s horn but ignores the warning, and the sword comes and takes him away, his death will be his own fault.

5Since he heard the sound of the ram’s horn but ignored the warning, his death is his own fault. If he had taken warning, he would have saved his life.
