For a full-blooded sex-life, the ancient Greeks felt, a man should have a wife and a concubine. The law-givers the world over called such sexual liberties- ADULTERY.
Imagine a case of a happily married man- intensely love by a devoted getting infatuated about a buxone damne (36: 24: 36) and when he holds her hand in a hot embrace there she lies dead in a cold- blood!..
Was this a planned cold-blooded murder?! Who designed it?! Could he hold his own devoted wife, much less another woman, in another manly embrace again???!!
This was the KASHAMAKASH (tense emotional conflict) of an adult- an adulterer in the eyes of law, a faithless husband for a wife and an ignominious brother for a sister on the threshold of a marriage.
