Exodus 21:29-32

But suppose the ox had a reputation for goring, and the owner had been informed but failed to keep it under control. If the ox then kills someone, it must be stoned, and the owner must also be put to death. However, the dead person’s relatives may accept payment to compensate for the loss of life. The owner of the ox may redeem his life by paying whatever is demanded. “The same regulation applies if the ox gores a boy or a girl. But if the ox gores a slave, either male or female, the animal’s owner must pay the slave’s owner thirty silver coins, and the ox must be stoned.
