What's Adultery? And what are the causes of adultery!

According to Strong's bible concordance, and all other biblical interpretation from the original texts, adultery is when a woman breaks wedlock. i.e A married woman having sex otherside marriage. Men were only considered to have commited adultery if they slept with a married woman. A married man having sex outside marriage was not considered adultery

ADULTERY
Is a criminal connection between persons who are engaged, one or both, to keep themselves wholly to others; and thus it exceeds the guilt of fornication, which is the same intercourse between unmarried persons. As the highest sin of its kind, and son including all other sins of the flesh, it is forbidden in the seventh commandment. Where polygamy was allowed, as among the ancient Jews, illicit intercourse between a married man and a woman who was married, nor betrothed, constituted not adultery, but fornication.

Fornication may be, in some sense, covered by a subsequent marriage of the parties; but adultery cannot be so healed. Hence God often compares himself to a husband jealous of his honor, Jer 31:32; and hence the forsaking of the true God is compared to fornication and adultery of the vilest kind, Jer 3:9; Eze 23:36-49.

By the Law of Moses, both the man and the woman who had committed adultery were punished with death, Le 20:10; 21:9; Joh 8:5. A woman suspected of this crime might, in order to clear herself, drink the "water of jealousy," as prescribed in Nu 5:1-31.
