Thematic Bible: The reward for not warning others

And at the end of seven days, the word of the Lord came to me: Son of man, I have made you a watchman to the house of Israel; therefore hear the word at My mouth and give them warning from Me. If I say to the wicked, You shall surely die, and you do not give him warning or speak to warn the wicked to turn from his wicked way, to save his life, the same wicked man shall die in his iniquity, but his blood will I require at your hand.

And the word of the Lord came to me, saying, Son of man, speak to your people [the Israelite captives in Babylon] and say to them, When I bring the sword upon a land and the people of the land take a man from among them and make him their watchman, If when he sees the sword coming upon the land, he blows the trumpet and warns the people, read more.
Then whoever hears the sound of the trumpet and does not take warning, and the sword comes and takes him away, his blood shall be upon his own head. He heard the sound of the trumpet and did not take warning; his blood shall be upon himself. But he who takes warning shall save his life. But if the watchman sees the sword coming and does not blow the trumpet and the people are not warned, and the sword comes and takes any one of them, he is taken away in and for his perversity and iniquity, but his blood will I require at the watchman's hand. So you, son of man, I have made you a watchman for the house of Israel; therefore hear the word at My mouth and give them warning from Me. When I say to the wicked, O wicked man, you shall surely die, and you do not speak to warn the wicked from his way, that wicked man shall die in his perversity and iniquity, but his blood will I require at your hand.
