Leviticus 20:10

Adulteress. Philo (de Josephus) says, whoever discovered a man in the very act, might kill him; and the Roman law allowed the same liberty, impune necato. But God requires a juridical process, and witnesses, as we see in the case of Susanna, (Daniel xiii.) and in that of the woman who was brought to our Saviour. One witness might authorize a person to put his wife away, and if he then retained her, he was esteemed a fool, Proverbs xviii. 23. But more witnesses were requisite before she could be put to death. They put their hands on the heads of the guilty, thus taking their blood upon themselves, if they accused them wrongfully. Solon allowed the husband to kill the adulterer. The woman was not permitted to wear any ornaments, or to enter any temple afterwards. If she did, any one might tear her clothes, and beat, but not kill her.
