The marriage covenant is physical, emotional, mental, financial, and spiritual bonding. Two become one. A covenant is a binding vow between two. A covenant reflects the nature of God who makes covenants with people. Therefore, God pays attention to marriage covenants.
Adultery is breaking a marriage covenant for an important part of the covenant is the one that becomes new during sexual union. The Father instructs his child to maintain discretion when the temptation of adultery promises delight (1-3).
Sexual temptation wears blinders. The sweet honey and smooth oil promise of the tempted do not see the hidden bitter gall and heart-splitting double-edged sword (4). Breaking the marriage covenant is the death of the two that become one (5). The beautiful matrix created dies and is buried. The temptation does not see these consequences (6). Therefore, know now the truth about adultery.
