'Warning' in the Bible

"Son of man, I have appointed you a watchman for the house of Israel. Whenever you hear a word from my mouth, you must give them a warning from me.

but there is one who hears the sound of the trumpet yet does not heed the warning. Then the sword comes and sweeps him away. He will be responsible for his own death.

He heard the sound of the trumpet but did not heed the warning, so he is responsible for himself. If he had heeded the warning, he would have saved his life.
