In the Bible, the snake in Eve’s story is called the serpent.
Genesis 3 describes the serpent as “more crafty” than the other wild animals God had made. It approaches Eve in the Garden of Eden, questions God’s command about the tree of the knowledge of good and evil, and persuades her to eat the fruit. Eve then gives some to Adam, leading to their expulsion from Eden.
The Bible does not give the creature a personal name such as “Satan” or “Lucifer.” “Serpent” is the actual term used in the Genesis narrative. Later Jewish and Christian interpretation often associates the serpent with Satan, especially because Revelation refers to “that ancient serpent,” but that identification is an interpretive development rather than the snake’s stated name in Genesis.
Another common mix-up is the fruit: Genesis never identifies it as an apple. The apple association developed later through artistic tradition and Latin wordplay.
