Revelation 20:8

Strongs #4105 πλανάω to make wander, lead astray

This does not mean literally "to deceive" (cf. Strong's #G538).

It is different from the Greek word for "deception" is ἀπάτη (apatē), a feminine noun meaning "deception," "trick," or "fraud." This is the word conveying the concept of misleading or deceiving someone, through trickery or manipulation or otherwise. In Ancient Greek literature, ἀπάτη appears frequently to describe acts of deceit, whether in contexts of warfare, interpersonal relationships, or moral discussions. For example, ἡ ἀπάτη τοῦ ἀνθρώπου translates as "the deception of the man." Related terms include ἀπατάω (apataō), a verb meaning "to deceive" or "to cheat," and δόλος (dolos), another noun for "deceit" or "trickery." In modern Greek, the term remains απάτη (apáti), carrying a similar meaning.
