Peter Pett's Commentary on the Bible
Leviticus 20:9-18
Crimes Which Deserve The Death Penalty (Leviticus 20:9).
“For every one who curses his father or his mother shall surely be put to death. He has cursed his father or his mother. His blood shall be on him.”
The first such crime is that of a man cursing his father or mother. This does not mean that he just swears about something they have done, or at them because they have annoyed or frustrated him. It refers rather to a man who seeks to put his father and mother under a specific curse. He calls on Yahweh to do the very opposite of what Yahweh has declared He will do. The man is not only dishonouring them, he is seeking to do them real harm, and dishonouring Yahweh.
The use of curses was widespread. A multitude of examples have been found in Egypt, and many could be bought and sold. The purpose of a curse was to use ‘occult' means to do someone harm. It would especially appeal to the weak who had no other means of vengeance.
In a patriarchal society where the father figure was the supreme authority this would have been a deliberate attempt to undermine tribal authority, and even to take over power for himself. It was a blow at the family structure, and if successful could have undermined the society in which he lived. The one who attempts something like this must be put to death. Such a person with such aims to carry out in such an evil way cannot be allowed to live, because of the harm he will do in destabilising society. And he has brought his blood on his own head. There will be no guilt on any who put him to death. The guilt will be on him.
“And the man who commits adultery with another man's wife, even he who commits adultery with his neighbour's wife, the adulterer and the adulteress shall surely be put to death.”
The next crime is adultery, where a man takes his neighbour's wife. In this case both he and the adulteress were to be put to death. Again it was a blow at the family which was the very basis of society.
“And the man who lies with his father's wife has uncovered his father's nakedness. Both of them shall surely be put to death. Their blood shall be on them.”
The third such crime was when a man lay with his father's wife, that is, had sexual relations with her. Both he and she were to be put to death. For it would be as if he has publicly stripped his father naked. A man's wife is one flesh with him (Genesis 2:24). To make her naked would be to make her husband naked. They have brought their blood on their own heads. Anyone who executes them is guiltless.
“And if a man lies with his daughter-in-law, both of them shall surely be put to death. They have wrought confusion. Their blood shall be on them.”
The same principle applied between a man and his daughter-in-law. If they had sexual relations, both were to be put to death. They would have mixed up the generations, causing ‘confusion', (for the son could become brother to his wife's son), and the man would have exposed his son to shame and ridicule. Again those who put them to death will bear no guilt. The guilt is on their own heads. In all these examples the destruction of family relationships is central.
“And if a man lies with mankind, as with womankind, both of them have committed abomination. They shall surely be put to death. Their blood shall be on them.”
For a man to have sexual relations with another man is an abomination. No other relationship is always described specifically as an abomination in this way, so it is clearly particularly hateful to God. And being in the midst of a passage dealing with sexual matters this refers to any practising homosexual relationship, not just to cultic practise. It is saying that there is no such thing as a Christian practising homosexual. This has nothing to do with whether a man has homosexual tendencies, it is speaking of a deliberate giving way to those tendencies. Those who do so shall ‘surely be put to death'. Again they have brought their blood on their own heads.
“And if a man take a wife and her mother, it is sexual wickedness. They shall be burned with fire, both he and they, that there be no wickedness among you.”
Equally guilty would be a man who had sexual relations with both his wife and her mother. This would be sexual wickedness. They are all three to be burned with fire. The burning may indicate a death of particular shame as devoted to destruction (as Achan was - Joshua 7). Or perhaps the thought is that they deserve the same thing as happened to worshippers of Molech. They have shown themselves worthy only of Molech.
“And if a man lie with a beast, he shall surely be put to death, and you shall slay the beast.”
The same principle applies to a man who has sexual relations with a dumb animal. Both he and the beast must be put to death. But it is not quite as abhorrent as a man who beds mother and daughter for the punishment is less horrific.
“And if a woman approach any beast, and lie down with it, you shall kill the woman, and the beast. They shall surely be put to death. Their blood shall be on them.”
A woman is no different. If she allows a beast to have sexual relations with her, both she and the beast must die. They shall surely be put to death. Their actions have brought their blood on themselves. There will be no bloodguilt for those who slay them. (The beast, if previously a clean one, is clearly not to be offered as a sacrifice).
“And if a man shall take his sister, his father's daughter, or his mother's daughter, and see her nakedness, and she see his nakedness, it is a shameful thing. And they shall be cut off in the sight of the children of their people. He has uncovered his sister's nakedness. He shall bear his iniquity.”
No man shall have sexual relations with a sister or half-sister by blood. It is a shameful thing and means that they must be cut off ‘in the sight of the children of Israel', presumably this indicates stoning. He must take the punishment for the evil he has done.
“And if a man shall lie with a woman having her sickness, and shall uncover her nakedness, he has made naked her fountain, and she has uncovered the fountain of her blood, and both of them shall be cut off from among their people.”
The one who deliberately lies with a woman during menstruation, while the blood is on her, shall be cut off from among the people, as shall also the woman, he because he has exposed her bleeding, she because she has uncovered her bleeding. Her bleeding is an uncleanness and related to death. It speaks of sin and death. It should be hidden and not exposed. To expose it is to deserve the death of which it speaks.
It is, however, possible that this does not refer to husband and wife, but to where a man forces a woman who is not his wife during her menstruation. By shaming her like this it is as if he had committed adultery.
These then (from Leviticus 20:2) are the major crimes which in God's eyes are worthy of death. They are so evil that they override the concept of the sacredness of life. Those who do them have forfeited the right to life.
