“"It was also said, 'Whoever divorces his wife, let him give her a certificate of divorce.' But I say to you that everyone who divorces his wife, except on the ground of sexual immorality, makes her commit adultery. And whoever marries a divorced woman commits adultery. "Again you have heard that it was said to those of old, 'You shall not swear falsely, but shall perform to the Lord what you have sworn.' But I say to you, Do not take an oath at all, either by heaven, for it is the throne of God, or by the earth, for it is his footstool, or by Jerusalem, for it is the city of the great King. And do not take an oath by your head, for you cannot make one hair white or black. Let what you say be simply 'Yes' or 'No'; anything more than this comes from evil.”
Introduction
In the Sermon on the Mount, Jesus speaks with bold clarity about the life of faithfulness within daily realities. Matthew 5:31-37 gathers two ancient teachings—on divorce and on oaths—and reframes them in light of God’s intent for truth-telling, integrity, and dependability. Jesus invites his listeners to pursue a simple, trustworthy manner of speech and lifestyle that honors God, protects human dignity, and cultivates trust within community. The passage challenges us to examine not only our actions but the inner desires that shape our promises and commitments, reminding us that genuine righteousness flows from the heart rather than from outward conformity alone.
Historical-Cultural Context and Authorship
The Gospel of Matthew presents Jesus immersed in Jewish teaching and communal life. In this section of the Sermon, Jesus speaks to listeners shaped by Mosaic law and rabbinic interpretation. Divorce in first-century Judea carried social and legal weight, often governed by a man’s permission rather than mutual fidelity, and oaths were commonly invoked to guarantee truth in complex social and religious transactions. Yet Jesus points to a higher principle: the integrity of one’s word before God, who sees the heart and the totality of one’s life. This teaching aligns with Matthew’s broader aim to present Jesus as the fulfillment of God’s promises, shaping a discipleship that transforms the ordinary speech and everyday choices of his followers.

Explanation and Meaning of the Text
- Verses 31-32 address divorce. The “certificate of divorce” reflects legal mechanisms of the time. Jesus tightens the stance, allowing divorce only on the ground of sexual immorality and expanding responsibility beyond the divorced spouse to the one who remarries. The underlying aim is to protect dignity, safeguard relationships, and reduce instability and harm caused by easy or ill-considered divorces.
- Verses 33-37 address oaths. Jesus rejects the culture’s habit of swearing by heavens, the earth, Jerusalem, or even one’s head to guarantee truth. He instructs that one’s word should be straightforward: let your “Yes” be yes and your “No” no. Anything more comes from evil, not because oaths are always wrong, but because a trustworthy, truthful life should render oaths unnecessary. The measure is honesty, consistency, and sincerity in speech, reflecting alignment with God’s own truthfulness.
- The overarching theme is integrity before God. Jesus calls his followers to live with transparent honesty, whose power comes from a heart surrendered to God. The goal is not legalism but a transformation of speech and conduct that protects relationships and honors the God who sees what is said and why it is said.
Devotional
We come to God with tender honesty, knowing that the Lord weighs not only our words but the motives behind them. Lord, help me to let my speech reflect your truthfulness and mercy, so that a simple “Yes” or “No” would carry the weight of integrity you desire. Lead me away from lukewarm promises and fear-driven oaths, into a life that trusts your strength and reflects your trustworthy character.
May your grace soften our hearts, so our everyday conversations become places of blessing—protecting the vulnerable, honoring commitments, and building trust within family, church, and community. Amen.
