Many people think the word “Satan” is simply a personal name, but in the Bible the word is actually a transliterated Hebrew term: ha-satan, meaning “the adversary,” “accuser,” or “opposer.”
The word satan means adversary. Whether that adversary is a human opponent, a heavenly accuser, or a specific spiritual enemy must be determined by the context of each passage.
While the word literally means ‘adversary,’ Scripture often personifies this adversary in a spiritual being opposing God’s purposes. Understanding the word’s meaning lays the foundation for recognizing the adversary as both a role and, in some contexts, a personified being.
Understanding who satan is in the Bible requires examining both the Old and New Testaments and the spiritual conflict described throughout Scripture.
What Does the Word “Satan” Mean?
The Hebrew word Satan means adversary, opponent, or accuser.
In the earliest Old Testament passages, the Hebrew phrase ha-satan literally means “the adversary” or “the accuser.” The definite article (ha) suggests a title or role rather than a personal name. In passages such as Job 1–2 and Zechariah 3:1–2, Satan appears as an accuser. Later biblical revelation increasingly associates Satan with a spiritual enemy who opposes God and humanity.
In the Old Testament, Satan first appears as an accuser before God in:
In the New Testament the word Satan is used in relation to an enemy opposing God’s kingdom — deceiving humanity, tempting people into sin, and resisting the Messiah.
The New Testament uses ‘Devil’ and ‘Satan’ for the same adversarial figure. ‘Diabolos’ (Devil) means ‘slanderer,’ while ‘Satan’ means ‘adversary,’ highlighting both opposition to God and a deceptive character
Satan in the Bible: Roles and Characteristics
The Bible portrays Satan as:
- The deceiver of the nations
- The tempter of humanity
- The accuser of believers
- The father of lies
- A spiritual enemy opposed to God’s truth
Main passages include:
- Matthew 4:1-11 — Satan (the adversary) tempts Jesus
- John 8:44 — Jesus calls the devil “a murderer from the beginning” and “the father of lies”
- Revelation 12:9 — Satan is symbolized as “the great dragon… that ancient serpent, who is called the devil and Satan, the deceiver of the whole world”
Genesis 3 describes a serpent who deceives Eve, leading humanity into sin. While the text itself does not explicitly identify the serpent, later Scripture makes this connection. Revelation 12:9 and Revelation 20:2 describe Satan as “that ancient serpent,” linking it directly to the deception in Eden.
Jesus also uses serpent imagery when addressing His opponents. In Matthew 23:33, He calls some religious leaders a “brood of vipers,” emphasizing their hostility, deceit, and alignment with spiritual opposition to God. This shows a consistent biblical pattern: those who oppose God’s truth are compared to serpents, making clear both danger and deception.
People Connected With Satan in Scripture
Several individuals and groups are described as coming under Satan’s influence through rebellion, deception, betrayal, or violence to oppose God’s purposes:
- Cain: 1 John 3:12 says Cain “was of the evil one” because he murdered his brother Abel out of hatred.
- Judas Iscariot: Luke 22:3 states that Satan entered Judas before he betrayed Jesus.
- Religious Leaders Opposing Jesus: Some leaders rejected Jesus and plotted to kill Him. In John 8:44, Jesus told His opponents: “You are of your father the devil, and your will is to do your father’s desires.” Jesus was addressing their specific actions of violence, deception, and rejection of truth — not an entire ethnicity. According to the Bible the people that stood against Jesus were amongst the Pharisees, the Sadducees, the scribes, the Herodians and the the chief priests and elders.

What Is the “Synagogue of Satan”?
The phrase “synagogue of Satan” appears in Revelation 2:9 and Revelation 3:9.
In context, these verses refer to groups persecuting early Christians while falsely claiming spiritual authority. Biblically and historically, this phrase should not be used as a racial or ethnic attack against Jewish people, because it has to do with religion. The New Testament defines opposition to God by actions and unbelief, not by ethnicity or ancestry.
Why Did Some People Want to Kill Jesus?
The Gospels explain that certain religious and political leaders saw Jesus as a threat because He challenged corruption and hypocrisy, claimed divine authority, attracted large crowds, and exposed false righteousness. The New Testament presents this conflict as both spiritual and political. Jesus taught that hatred, lies, and murder reflect the influence of the enemy of God rather than the will of God.
Final Thoughts: Who Is Satan According to the Bible?
The Bible uses the word Satan in relation to an adversary who opposes truth, righteousness, and God’s kingdom. The word embodies deception, accusation, rebellion, and spiritual darkness.
While Scripture teaches the reality of Satan and spiritual opposition, the central focus of the Bible are not the enemies but God’s plan of redemption. The gospel proclaims that through Jesus Christ, forgiveness, reconciliation with God, and victory over sin and death are available to all who believe.
