Leviticus 20:10-12

Lev 20:10 “If a man commits adultery with the wife of his neighbour, both the adulterer and the adulteress will surely be put to death.
Lev 20:11 If a man lies with his father’s wife, he has uncovered his father’s nakedness; both of them will surely be put to death; their blood is upon them.
Lev 20:12 If a man lies with his daughter-in-law, both of them will surely be put to death; they have committed perversion; their blood is upon them.

both of them

All three of the instances of sexual immorality in these verses represent what in today’s society is called sexual activity between mature, consenting adults. We are taught that such activity should not be regulated by our governments at all. This cultural conditioning makes us somewhat embarrassed that the Bible not only regards such acts as immoral, but that here the death penalty is prescribed for those who disregard the rule. But if we dare to look at this from God’s perspective, we might see that this activity is not just a choice between mature consenting adults. It is a choice to pervert God’s plan. We can add many other ways that our society and culture today has chosen to rebel against God’s plan for the family. The fact is, the Israelites had covenanted as a nation to obey God’s law, as given by Moses. To rebel at this stage was not simply a personal choice of lifestyle. It was high treason. The death penalty for high treason is legitimate.

LORD, protect us from our liberty. Keep us from choosing to rebel against you together.
