God killed Aaron's sons by burning them to death and then told Aaron not to mourn them. This was used in a Watchtower video as an example for parents to shun their disfellowshipped children. (The video has since been deleted at JW.org do to a lawsuit in Norway addressing the shunning of disfellowshipped children by their parents.)
