John 8:5 - Coke's Commentary on the Holy Bible

Now Moses in the law commanded— The law, Leviticus 20:10. Deuteronomy 22:22 required in the general, that adultery should be punished with death, but did not determine the kind of it: only because it is ordered, Deuteronomy 22:23-24 that the betrothed damsel guilty of adultery should be stoned, it is supposed that in process of time this kind of death was appropriated to such offenders; and that the punishment of the married adulteress, Leviticus 20:10 was interpreted to mean strangling: agreeably to these suppositions, it has been conjectured, that the woman now before Jesus was only betrothed; but the distinction has no foundation; for it is evident from Ezekiel 16 that the proper punishment of all kinds of adultery was stoning, John 8:38. I will judge thee as women that break wedlock are judged; and John 8:40. They shall stone thee with stones. Besides this, we find Philo, and the ancient Christian fathers, using the phrases, "those that were stoned," and "those that were punished for adultery," as synonymous terms.
