Ezekiel 7:14; Ezekiel 33:3; Ezekiel 33:6

14 They have blown the trumpet, even to make all ready ; but none goeth to the battle: for my wrath is upon all the multitude thereof.
3 If when he seeth the sword come upon the land, he blow the trumpet, and warn the people;
6 But if the watchman see the sword come , and blow not the trumpet, and the people be not warned ; if the sword come , and take any person from among them, he is taken away in his iniquity; but his blood will I require at the watchman's hand.
