5: Now Moses in the law commanded us to stone such a one. But what
sayest thou?
Moses in the law, &c. The punishment of adultery commanded by Moses was death, Lev 20:10 Deut 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 See "Mt 21:35"-44
The punishment for adultery varied. In some cases it was strangling. In the time of Ezekiel Ezek 16:38ff 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.
