Biblical Fact - The ninth commandment: “Do not let thyself lust after thy neighbor’s wife!”
The
ninth commandment as expressed in this topic points toward purity of heart,
faithfulness, and self-control. While the wording “Do not let thyself lust
after thy neighbor’s wife” closely reflects the teaching against coveting
another person’s spouse, the Bible repeatedly warns believers about sinful
desire, adultery, and lustful thoughts. God calls His people not only to
outward obedience but also to inner holiness.
This
command teaches that sin often begins in the heart before it appears in
actions. The Bible encourages believers to guard their thoughts, honor
marriage, and pursue righteousness.
Understanding
Lust in the Bible
Lust
is an intense sinful desire that leads a person away from God’s will. In
Scripture, lust is not limited to physical actions; it also includes inward
thoughts and desires.
Jesus
explained that sin begins within the heart:
“But
I say unto you, That whosoever looketh on a woman to lust after her hath
committed adultery with her already in his heart.”
—
Matthew 5:28 (KJV)
This
teaching reveals that God examines not only human behavior but also human
motives and desires.
The
Command Against Coveting
One
of the Ten Commandments directly warns against desiring another man’s wife:
“Thou
shalt not covet thy neighbour's wife, nor his manservant, nor his maidservant,
nor his ox, nor his ass, nor any thing that is thy neighbour's.”
—
Exodus 20:17 (KJV)
This
verse emphasizes contentment and respect for others. Coveting destroys
relationships, creates jealousy, and opens the door to greater sin.
The
same command is repeated later:
“Neither
shalt thou desire thy neighbour's wife, neither shalt thou covet thy
neighbour's house…”
—
Deuteronomy 5:21 (KJV)
Lust
and Adultery
The
Bible consistently connects lustful desire with adultery. Adultery is a serious
sin because it breaks covenant relationships and dishonors God.
“Marriage
is honourable in all, and the bed undefiled: but whoremongers and adulterers
God will judge.”
—
Hebrews 13:4 (KJV)
The
book of Proverbs contains many warnings about immoral desire and
unfaithfulness.
“Can
a man take fire in his bosom, and his clothes not be burned?”
—
Proverbs 6:27 (KJV)
This
verse illustrates how dangerous sinful passion can become when it is
entertained.
David
and Bathsheba: A Biblical Example
One
of the clearest biblical examples of lust leading to destruction is the story
of King David and Bathsheba.
David
saw Bathsheba, desired her, and committed adultery, even though she was the
wife of Uriah.
“And
David sent messengers, and took her; and she came in unto him, and he lay with
her…”
—
2 Samuel 11:4 (KJV)
David’s
sinful desire eventually led to deception, guilt, and tragedy. This account
demonstrates how unchecked lust can affect families, leadership, and spiritual
life.
Guarding
the Heart and Mind
The
Bible teaches believers to guard their hearts carefully because thoughts
influence actions.
“Keep
thy heart with all diligence; for out of it are the issues of life.”
—
Proverbs 4:23 (KJV)
Christians
are encouraged to focus on things that are pure and honorable.
“Whatsoever
things are true… honest… just… pure… think on these things.”
—
Philippians 4:8 (KJV)
Avoiding
temptation often requires wisdom, discipline, and prayer.
The
Importance of Faithfulness in Marriage
Marriage
is presented in Scripture as a sacred covenant established by God. Husbands and
wives are called to love and honor one another faithfully.
“Therefore
shall a man leave his father and his mother, and shall cleave unto his wife:
and they shall be one flesh.”
—
Genesis 2:24 (KJV)
Faithfulness
reflects God’s design for love, trust, and unity within marriage.
Victory
Over Temptation
The
Bible does not leave believers without hope. God provides strength to resist
temptation and pursue holiness.
“There
hath no temptation taken you but such as is common to man: but God is
faithful…”
—
1 Corinthians 10:13 (KJV)
Through
prayer, Scripture, accountability, and the guidance of the Holy Spirit,
believers can overcome sinful desires.

Conclusion
The
biblical command against lusting after another person’s spouse is ultimately a
call to holiness, faithfulness, and purity of heart. God desires His people to
honor marriage, reject sinful desire, and cultivate righteous thoughts. The
Bible reminds believers that true obedience begins within the heart and that
God offers grace and strength to overcome temptation.
By
walking closely with God and filling the mind with His truth, Christians can
pursue lives marked by integrity, purity, and faithful love.
Reflection
The
command against lusting after another person’s spouse reminds believers that
God cares deeply about the condition of the heart. Sin is not only about
outward actions; it also begins with thoughts, desires, and attitudes hidden
within. Jesus taught that lustful thinking itself can lead a person away from
holiness and faithfulness.
In
a world filled with temptation, comparison, and immoral influences, this
command calls Christians to pursue purity and self-control. It encourages
believers to value people with honor and respect rather than selfish desire.
The Bible repeatedly shows that unchecked lust can destroy trust, families,
peace, and spiritual intimacy with God.
At
the same time, Scripture offers hope. God does not simply expose sin—He also
provides forgiveness, wisdom, and strength to overcome temptation. Through
prayer, Scripture, and dependence on the Holy Spirit, believers can grow in
purity and faithfulness.
