Matthew 19:6

Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.

Matthew 19:6 (KJV)

Context

Jesus speaks these words in a debate with the Pharisees, who ask whether it is lawful for a man to divorce his wife for any reason. He answers by pointing back to the creation account, quoting Genesis 2:24 to show that God designed marriage as a lifelong union. The immediate setting is Matthew 19:1-9, where Jesus corrects the Pharisees’ testing question by appealing to God’s original purpose rather than to human custom.

Meaning

The verse has two parts. First, “they are no more twain, but one flesh” means that a husband and wife, who were two separate people, become a single entity through marriage. This “one flesh” union is rooted in Genesis 2:24, which Jesus quotes in the preceding verse. It involves the whole person—body, soul, and life—not merely a physical or legal arrangement. Second, “What therefore God hath joined together, let not man put asunder” declares that marriage is a divine institution. The bond is made by God Himself, so it is sacred and not to be dissolved by human authority, whether the husband, another person, or the state. The contrast between God and man shows that marriage is not merely a civil contract but a covenant in which God is directly involved.

Biblical connections

The phrase “one flesh” also appears in Ephesians 5:28-29, where husbands are told to love their wives as their own bodies, reinforcing the idea that the marital union is as close as the relationship between a person and their own body. Jesus’ teaching here also connects to the creation account in Genesis, where God establishes marriage before the fall, indicating that it is part of His original design for humanity.

Application

This verse calls believers to honor marriage as a sacred covenant designed by God, meant to be a lifelong commitment between a man and a woman. It also shows the seriousness of divorce: Jesus later explains that Moses permitted divorce because of hard hearts, but it was not God’s original intention. While divorce is a painful reality, the Bible also emphasizes forgiveness, reconciliation, and the possibility of restoration in broken relationships. Believers are encouraged to seek God’s help in maintaining the union He has established and to extend grace when marriages fall short of His design.

Reflection

Marriage is not a human invention but a divine joining. This truth should shape how we view our own marriages and how we support others in theirs. It also reminds us that God’s standards are higher than human concessions, and His grace is available to help us live them out.
