4) The prohibition of immorality and promiscuity. Respect the institution of marriage. Marriage is a most Divine act. The marriage of a man and a woman is a reflection of the oneness of G-d and His creation. Disloyalty in marriage is an assault on that oneness. Wholesome families are a basis of healthy communities and societies. Immorality leads to inner decay. (Gen. 2:24)
The relevant verse in Genesis 2:24 states:
"Therefore a man shall leave his father and his mother and cling to his wife, and they shall become one flesh."
The phrase "cling to his wife, " comes to teach us that he shall have relations with his own wife and not another man’s wife.
It is also a righteous practice, and it adds to the level of the marriage bond.
