Bible Verses About Watchman: Alarm of, given by trumpets

Now if, upon seeing the sword coming against that country, he blows the shofar and warns the people;

then, if the sword comes and takes away someone who heard the sound of the shofar but paid no attention to it, the responsibility for that person's death will be his own -

he heard the shofar but paid no attention, so the responsibility for his death is his own; whereas if he had paid attention, he would have saved his life.

But if the watchman sees the sword coming and does not blow the shofar, so that the people are not warned; and then the sword comes and takes any one of them, that one is indeed taken away in his guilt, but I will hold the watchman responsible for his death.'
