Job 31:11 - Matthew Poole's English Annotations on the Holy Bible

To wit, adultery, whether committed by choice and design, or by the solicitation of the woman, Job 31:9. Heb. an iniquity of the judges, i.e. which belongs to them to take cognizance of, and to punish, and that with death; and that not only by the law of Moses, Deuteronomy 22:22, but even by the law of nature, as appears from the known laws and customs of heathen nations in that case. See also Genesis 38:24. This is opposed to those secret and lesser sins, which are only known to and punished by God.
