'Trumpet' in the Bible

‘They have blown the trumpet and made everything ready, but no one is going to the battle, for My wrath is against all their multitude.

and he sees the sword coming upon the land and blows on the trumpet and warns the people,

then he who hears the sound of the trumpet and does not take warning, and a sword comes and takes him away, his blood will be on his own head.

He heard the sound of the trumpet but did not take warning; his blood will be on himself. But had he taken warning, he would have delivered his life.

But if the watchman sees the sword coming and does not blow the trumpet and the people are not warned, and a sword comes and takes a person from them, he is taken away in his iniquity; but his blood I will require from the watchman’s hand.’
