Marriage involves a relationship between a man and a woman, but what constitutes a scriptural marriage? Scripturally speaking, it is not merely “flesh joining flesh.” This is plain in that a man could marry a wife only to find that she had been unfaithful with another man to whom she was not married (Deuteronomy 24:1; Matthew 5:32). It is also clear that Shechem defiled Dinah, but then asked if she could become his wife (Genesis 34:1-4). The woman at the well had an improper relationship with a man, but the Lord declared that that particular man was not her husband (John 4:16-18). Instead, marriage occurs when God joins a man and a woman (Genesis 2:21-24; Mark 10:9), and it is often established by a ceremony with vows given to each other (Matthew 22:1-13; John 2:1-2).
Our verbal communications involve the words that spring forth from our mouths. No doubt, the Lord considers these communications important and we should too. In today’s passage, the Lord gave some specific insights concerning His expectations of our communication. First, He wants our communication to be short and to the point – “let your communication be, Yea, yea; Nay, nay” (Matthew 5:37; see also Proverbs 10:19; Ecclesiastes 5:3, 7). Second, our word should be validated without the necessity of certifying it with vows, oaths, and swearing. In the context of the passage, the Lord Jesus forbade swearing “by heaven” (Matthew 5:34), “by the earth” (Matthew 5:35), or “by thy head” (Matthew 5:36). When we swear by these things, we put ourselves in danger of condemnation (James 5:12). Let your nay be nay and your yea be yea!
