Ezekiel 33:29
Then shall they know that I am the LORD, when I have laid the land most desolate because of all their abominations which they have committed.
More from Ezekiel 33
Again the word of the LORD came unto me, saying,
Son of man, speak to the children of thy people, and say unto them, When I bring the sword upon a land, if the people of the land take a man of their coasts, and set him for their watchman:
If when he seeth the sword come upon the land, he blow the trumpet, and warn the people;
Then whosoever heareth the sound of the trumpet, and taketh not warning; if the sword come, and take him away, his blood shall be upon his own head.
He heard the sound of the trumpet, and took not warning; his blood shall be upon him. But he that taketh warning shall deliver his soul.
