'Warning' in the Bible

then he opens [the] ear of men, and {he frightens them with a warning}

And if you warn him, the righteous, not to sin, and [the] righteous does not sin, surely he will live, for he heeded a warning. And you will have saved your life."

And it will be [an] object of taunting and [an] object of mockery, a warning and a horror to the nations that [are] around you whenever I execute judgments against you in anger and in wrath and in furious punishments! I, Yahweh, have spoken!

and {anyone who listens} hears the sound of the horn and {he does not take warning} and [the] sword comes and it takes him, his blood will be on his [own] head.

[For] he heard the sound of the horn and he did not take warning; his blood will be on him. But [if] he took warning, he saved his life.

And in his place a despicable person will arise on whom they have not conferred the majesty of [the] kingdom, and he will come in {without warning} and he will seize [the] kingdom by deceit.

And warning him sternly, he sent him away at once.

Therefore be on the alert, remembering that night and day [for] three years I did not stop warning each one [of you] with tears.
