Exodus 20:14 - Ellicott's Commentary On The Whole Bible

Thou shalt not commit adultery. — Next to the duty of respecting a man’s life is placed that of respecting his domestic peace and honour. Adultery is an invasion of the household, a destruction of the bond which unites the family, a dissolution of that contract which is the main basis of social order. It was forbidden by all civilised communities, and in uncivilised ones frequently punished with death. The Mosaic enactments on the subject are peculiar chiefly in the absolute equality on which they place the man and the woman. Adulterers are as hateful as adulteresses, and are as surely to be put to death (Leviticus 20:10; Deuteronomy 22:22-24, &c.). The man who acts treacherously against “the wife of his covenant” is as great a sinner as the woman who breaks the marriage bond (Malachi 2:14-16). There is “no respect of persons” and no respect of sexes with God.
