Alma 14:27

And it came to pass that so great was their fear, that they fell to the earth, and did not obtain the outer door of the prison; and the earth shook mightily, and the walls of the prison were wrent in twain, so that they fell to the earth; and the Chief Judge, and the Lawyers, and Priests, and teachers which smote upon Alma and Amulek, were slain by the fall thereof.

They were so afraid that they fell to the ground. They couldn’t get to the outside door of the prison. The earth shook hard and the prison walls split in half. The walls fell to the ground. The chief judge and the lawyers, priests, and teachers who had hit Alma and Amulek were killed by the falling walls.

Terror seized them so completely that they collapsed before reaching the prison door. The earth shook violently. The prison walls split in two and came crashing down. The chief judge, the lawyers, priests, and teachers who had beaten Alma and Amulek were killed by the falling walls.
