But no human being can tame the tongue

James speaks of the tongue as if it were a wild animal. Here "tongue" represents a person's desire to speak evil thoughts. (See: rc://en/ta/man/translate/figs-metaphor and rc://en/ta/man/translate/figs-metonymy)

It is a restless evil, full of deadly poison

James speaks of the harm that people can cause by what they say as if the tongue were an evil and poisonous creature that can kill people. Alternate translation: "It is like a restless and evil creature, full of deadly poison" or "It is like a restless and evil creature that can kill people with its venom" (See: rc://en/ta/man/translate/figs-metaphor)
