A serpent plays an important role in Genesis, the first book of the Bible, and in Revelation, the last book. Scripture also mentions them in other places in the Old and New Testaments that are important to doctrines like sin and salvation. However, the term “serpent” is not a scientific designation, which leaves many readers to wonder what kind of creature the Bible refers to when it uses the word.
In the Bible, serpents are snakes. The Old Testament uses the Hebrew word for “snake” (nachash) to describe an animal. In Genesis 3, Satan embodies a snake when talking with Eve. The New Testament uses the Greek word for “snake” (ophis) to describe an animal, evil people, and Satan.

Why do some translations say “serpent” not “snake”?
“Serpent” is the traditional English translation of the Hebrew word that first appears at the beginning of Genesis 3:1. “Now the serpent was more crafty than any other beast of the field that the Lord God had made” (ESV). The NIV, NLT, KJV, NKJV, and the NASB all translate the word “serpent.” However, a few translations choose the word “snake” instead.
|CEV||The snake was sneakier than any of the other wild animals that the LORD God had made.|
|GNT||Now the snake was the most cunning animal that the LORD God had made.|
|NAB||Now the snake was the most cunning of all the wild animals that the LORD God had made.|
One Bible scholar writes, “The first serpent in Scripture is the subtle creature of Gn. 3, used by Satan to alienate man from God (Rom. 16:20; 2 Cor. 11:3), controlled by the devil like the demons in men and swine in NT days.”
He continues: “For its part, the serpent was put under a curse that it would never rise above its (already customary) creeping posture (Gn. 3:14). The serpent thus remained the biblical symbol of deceit (Mt. 23:33), and the arch-deceiver himself is ‘that old serpent’ (Rev. 12:9; 14-14; 20:2).” 
The serpent or snake in Paul’s writings
The Bible identifies the serpent with Satan in multiple passages. The Apostle Paul wrote one of the most explicit statements about it in 2 Corinthians 11:3, “But I am afraid that as the serpent deceived Eve by his cunning, your thoughts will be led astray from a sincere and pure devotion to Christ” (ESV). The NIV, NLT, KJV, NKJV, and the NASB all translate the word “serpent.”
|Translation||2 Corinthians 11:3|
|CEV||But now I fear that you will be tricked, just as Eve was tricked by that lying snake. I am afraid that you might stop thinking about Christ in an honest and sincere way.|
|GNT||I am afraid that your minds will be corrupted and that you will abandon your full and pure devotion to Christ–in the same way that Eve was deceived by the snake’s clever lies.|
|NAB||But I am afraid that, as the serpent deceived Eve by his cunning, your thoughts may be corrupted from a sincere [and pure] commitment to Christ.|
The serpent or snake in Revelation
Though John refers to the serpent multiple times in Revelation, 12:9 is the key to knowing its true identity. “And the great dragon was thrown down, that ancient serpent, who is called the devil and Satan, the deceiver of the whole world — he was thrown down to the earth, and his angels were thrown down with him” (ESV). The NIV, NLT, KJV, NKJV, and the NASB all translate the word “serpent.”
Of the three translations that refer to the creature as a “snake” in Genesis 3, only one retains the term in Revelation 12:9. The GNT and NAB may use the word “serpent” in Revelation because translators likely considered the writing style to be apocalyptic literature. In contrast, the genre of Genesis is historical narrative.
|CEV||Yes, that old snake and his angels were thrown out of heaven!|
|GNT||The huge dragon was thrown out–that ancient serpent, named the Devil, or Satan, that deceived the whole world. He was thrown down to earth, and all his angels with him.|
|NAB||The huge dragon, the ancient serpent, who is called the Devil and Satan, who deceived the whole world, was thrown down to earth, and its angels were thrown down with it.|
The German Reformer Martin Luther once said, “The devil was permitted to enter beasts, as he here entered the serpent in which Satan was and in which he conversed with Eve.”
