Question: where in the bible does it talk about receiving the mark of the beast?
Answer: In Revelation 13:5–8, the beast was given a mouth speaking in blasphemies against God and his name. Inscriptions have been found in Ephesus in which Nero is called "Almighty God" and "Savior". In verse 4, the beast is worshiped by the world alongside the dragon that gave it authority.
