This is a key phrase in the Song of Solomon (2:16; 6:3; 7:10). The couple belonged to no one else but to each other. Certainly, Solomon would have done well to have continually acknowledged this truth and not to have turned his affections to other wives.
The New Testament often speaks of the unity shared by man and wife (Matthew 19:6; Hebrews 13:6). The Shulamite maiden in the Song of Solomon had the confidence that her beloved belonged to her. Should not every wife live with this same confidence? Also, she left no doubt in his mind that she was his. He needed not concern himself that she might have intentions of being unfaithful to him.
When individuals make commitments to one another, they also make commitments to God. God sees and knows what people do and whether they are indeed faithful. The road to unfaithfulness begins when one does not control lusts. This is why Job said that he had “made a covenant” with his eyes. Looking upon a virgin was the beginning of the road to unfaithfulness, and Job knew it (Job 31:1). This is why Jesus taught so strongly against lust (Matthew 5:27-28).
The words, “I belong to you,” are only words unless he or she intends to back up the statement with diligent effort to remain faithful. The foundation for this is to control one’s lusts (James 1:13-14). Most say, on their wedding day, “until death do we part.” Committed couples mean it!
