Defining ‘Dumb’ and ‘Spirit’ in the Biblical Context

Literal vs Figurative Meaning of ‘Dumb’

In the Bible, the word “dumb” is used both literally and figuratively. The literal meaning refers to being unable to speak, often due to a physical affliction or muteness. However, “dumb” is more commonly used in a figurative sense to describe someone who is silent, whether by choice or due to supernatural causes.

Some key examples of the literal usage of “dumb” in Scripture include:

  • Isaac’s son Jacob deceiving his father to steal his brother’s blessing, after which Isaac “trembled violently” and told Esau, “Your brother came deceitfully and has taken away your blessing.” And Esau said, “Is he not rightly named Jacob? For he has cheated me these two times.

    He took away my birthright, and behold, now he has taken away my blessing.” Then he said, “Have you not reserved a blessing for me?” Isaac answered and said to Esau, “Behold, I have made him lord over you, and all his brothers I have given to him for servants, and with grain and wine I have sustained him.

    What then can I do for you, my son?” Esau said to his father, “Have you but one blessing, my father? Bless me, even me also, O my father.” And Esau lifted up his voice and wept. Then Isaac his father answered and said to him: “Behold, away from the fatness of the earth shall your dwelling be, and away from the dew of heaven on high.

    By your sword you shall live, and you shall serve your brother; but when you grow restless you shall break his yoke from your neck.” (Genesis 27:33-40)

  • Moses pleading with God after being called to lead the Israelites out of Egypt: “Pardon your servant, Lord. I have never been eloquent, neither in the past nor since you have spoken to your servant. I am slow of speech and tongue.” (Exodus 4:10)

In contrast, the figurative use refers to supernatural silencing or refraining from speaking. Themute demon in Luke 11:14 is the prime biblical example: “Jesus was driving out a demon that was mute. When the demon left, the man who had been mute spoke, and the crowd was amazed.”

This passage suggests evil spirits could afflict people with an inability to speak.

Spirits as Supernatural Beings in the Bible

The Bible presents living “spirit beings” as part of God’s creation, including both good and evil spirits. These supernatural creatures sometimes interact with people in overt and subtle ways. Specific categories of spirits named in Scripture include:

  • Angels – Heavenly servants of God who deliver messages and protect humans.
  • Demons – Fallen angels who rebelled against God and seek to oppress people.
  • The Holy Spirit – The Spirit of God empowering believers with spiritual gifts.

A key text differentiating these categories is Ephesians 6:12: “For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.”

This underscores that demons have destructive spiritual influences, while angels and the Holy Spirit have positive impacts.

The Gospels document dozens of encounters between Jesus and demons possessing and afflicting people. Christ repeatedly rebukes them and casts them out through His divine authority. He also sends out 72 disciples with power to expel many demons (Luke 10:17).

Acts 16 recounts the Apostle Paul commanding a troublesome spirit to leave a slave girl it had possessed. These and similar accounts reveal spirits can dominate people’s minds and bodies.

Key Biblical Passages Referencing ‘Dumb Spirits’

Mark 9:17-27 – The Dumb Spirit that Convulses a Boy

This passage describes a spirit that made a boy unable to speak and caused him to convulse violently. The disciples had tried unsuccessfully to drive out the spirit, but Jesus was able to cast it out after the boy’s father pleaded for help, saying “if you can do anything, have compassion on us and help us.”

After rebuking the spirit, Jesus commanded it to come out, and the spirit threw the boy into a severe convulsion before leaving him. Jesus then took the boy by the hand and lifted him to his feet, healed.

Matthew 9:32-33 – The Dumb Man Possessed by a Demon

This short passage simply states that “while they were going out, behold, a dumb man possessed by a demon was brought to him. And when the demon had been cast out, the dumb man spoke.” This shows that muteness or inability to speak can be a symptom of demonic possession, which Jesus was able to cure by casting out the demon.

Luke 11:14 – The Dumb Spirit Cast Out by Jesus

In this verse, Jesus was casting out a demon that was dumb/mute, and when the demon had gone out, the man who had been mute spoke. The crowds marveled, but some accused Jesus of casting out demons by the ruler of demons.

Jesus responded that a house divided against itself cannot stand – arguing that he did not derive his power from Satan.

Some key themes that emerge from these representative passages:

  • Demonic entities could possess people and render them mute/dumb/unable to speak
  • Casting these ‘dumb spirits’ out restores speech and healing
  • Jesus was shown to have power and authority over these afflicting spirits

Though not as commonly referenced today, these passages give insight into biblical accounts of dumb/mute spirits that deprived those they possessed of speech. Further historical analysis could examine how these manifestations were interpreted over time.

Historical Context on Exorcism and Beliefs About Dumbness

Pagans Viewed Some Disabilities as Caused by Spirits

In ancient pagan cultures, certain disabilities like deafness, blindness, and the inability to speak (dumbness) were sometimes attributed to the work of evil spirits. It was believed that these malevolent supernatural forces could take over a person’s body and impair their senses or abilities.

For example, in Ancient Greece and Rome, there were spirits known as empusae said to prey on human victims at night by depriving them of their voice or hearing. Dumbness or muteness was known as “having an empusa” and thought to be caused by one of these wicked creatures.

Similarly, in Germanic pagan traditions, there were dark elves like mara and alp believed to torment sleepers by inducing nightmares and robbing them of speech. Across pagan cultures, the cure was usually some ritual or exorcism rite to drive out the invading spirit.

Exorcism Rites in Early Judaism and Christianity

As monotheistic traditions emerged, the idea of demonic possession and exorcism rites continued. Early Judaism accepted the belief that spirits could inhabit objects or people’s bodies and cause afflictions like inability to hear or speak properly.

The Dead Sea Scrolls describe exorcism rituals, indicating Jews did perform rites of deliverance to free those seen as possessed. And in the Synoptic Gospels, Jesus performs several exorcisms, including on a mute man, often interpreted by biblical scholars as liberation from an evil spirit causing his inability to speak (Matthew 9:32-33).

So from pagan antiquity through early Christianity, many cultures shared conceptions of afflictions like muteness or deafness having a supernatural cause, whether an invading demon or wicked spirit. A common solution was an exorcism ritual to drive out the invading entity.

Of course, today the medical community recognizes such disabilities stem from genetic, biological and physiological causes – not demonic forces. But these ancient beliefs provide insight into how some ancient peoples made sense of and responded to disabilities not well understood at the time.

Remnants of the beliefs persist in some cultures even today.

Interpreting the Meaning for Today’s Readers

Distinguishing Spiritual vs Medical Causes of Conditions

When interpreting biblical references to conditions potentially caused by “dumb” or “deaf” spirits, it’s important to distinguish spiritual causes from medical ones with wisdom and nuance (1 Corinthians 12:8-10).

Many conditions, from epilepsy to some mental illnesses, were historically attributed to spiritual forces but today have clear biological or psychological underpinnings. While we cannot definitively rule out spiritual elements, assuming conditions are caused by demons or possession often leads to stigma and harm.

However, completely dismissing spiritual aspects risks ignoring nuances in some difficult cases. Studies show a small percentage of patients with schizophrenia, for example, have chronic auditory verbal hallucinations refractory to medications and psychotherapy.

Other analyses indicate modern medicine does not have all the answers, and some turn to religion or spirituality to make sense of and find comfort in their suffering. While secular help should be sought first, space should exist to allow divine encounters where appropriate.

Approaching Stories About Exorcism with Nuance

Biblical accounts of exorcisms, like Jesus’ healing of the Gerasene demoniac (Luke 8:26-39), underscore the importance of approaching stories about the demonic carefully. Though intended to display Christ’s power, such stories have been used throughout history to justify mistreatment of those considered “possessed.

The compassion Jesus shows, seeing the humanity within those suffering, provides a model for how we can approach exorcism narratives with more empathy today.

However, we must also acknowledge real spiritual warfare and suffering do exist. As Paul writes, “For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms” (Ephesians 6:12).

Accounts of possession and exorcism remind us this struggle is real for many believers worldwide. Dismissing their experiences can isolate them further. We must let the Spirit guide how we interpret the mystery of suffering in the tension between the natural and supernatural.


As we have seen, the biblical phrase ‘dumb spirit’ stems from a worldview attributing muteness and other conditions to demonic influence. While a modern reader may explain these passages naturalistically, the text suggests intended literal belief in spirits causing disability.

Examining this cultural context carefully allows us to interpret the meaning of these ancient stories with more wisdom and nuance. Stories of Jesus’ power over afflicting spirits can still speak profound truth about God’s care for suffering people today.
