E l'uomo che commette adulterio con la moglie di un altro, che commette adulterio con la moglie del suo prossimo, saranno certamente messi a morte l'adultero e l'adultera.
Leviticus
With your friends wife you shall not lie carnally, to defile yourself through her.
Deuteronomy
If a man is found having intercourse with a woman who is the wife of a man, even both of them shall die—the man who had intercourse with the woman and the woman—and you will eliminate the evil from Yisroel.
