Slay the sin offering ... and the priest shall take of the blood thereof with his finger, and put it upon the horns of the altar of burnt offering and shall pour out all the blood. 4:33
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.)
