Moses in the law ... - The punishment of adultery commanded by Moses was death, Leviticus 20:10; Deuteronomy 22:22. The particular manner of the death was not specified in the law. The Jews had themselves, in the time of Christ, determined that it should be by stoning. See this described in the notes at Matthew 21:35, Matthew 21:44. The punishment for adultery varied. In some cases it was strangling. In the time of Ezekiel Ezekiel 16:38-40 it was stoning and being thrust through with a sword. If the adulteress was the daughter of a priest, the punishment was being burned to death.
