And if a man beats his male or female servant with a rod, so that he dies under his hand, he shall surely be punished. Notwithstanding, if he remains alive a day or two, he shall not be punished; for he is his property.
In the first place, how could God allow a slave owner to beat his slave at all? To answer this question, we must remember who many of the Old Testament slaves were. They were members of the wicked, sinful nations who had been delivered into the hands of the Israelites because of their immorality. Suppose that a slave from one of those nations had made up his mind to do as much damage to his owner as possible. The slave had the option of running away to a gentler owner whenever he wished (Deuteronomy 23:15-16). However, suppose that he chose to stay and steal from the owner, or break the owners equipment intentionally, or destroy the owners crops. What could the owner do to stop such sabotage? Herb Vander Lugt put it like this:
Then, too, no matter how well the slaves were treated, some might have been rebellious and defiant. Forgetting that they were alive because they were taken as war captives instead of being executed, they might have blamed their master for their slave status. They might have shown their resentment by destroying property, abusing fellow slaves, or refusing to work. The master may have had no other way to bring his slave in line than to use physical punishment (1999, p. 17).
As appalling as it is to the sensitivities of most United States citizens, many countries still employ some type of beating or bodily harm to deter crime (some readers may recall the controversy over caning in Singapore in the early 1990s). When a modern-day prisoner violates rules while incarcerated, more stringent punishment (such as solitary confinement) often is required. If a slave deserved the death sentence, yet was allowed to live under certain conditionsand then did not comply with those conditionswould it be feasible to suggest that his death sentence could be reinstated? Even though it seems harsh to us, Exodus 21:20 does not militate against the justice of God.
