Women captives are to pare their fingernails (Deut. 21: 12).
Iron nails used by builders are mentioned by Isaiah (41: 7) and Jeremiah (10: 4) in a sarcastic description of the construction of idols. Nails were sometimes used by the Romans for fastening the victims of crucifixion and in 1968 Israeli archaeologists discovered, in a cemetery on the Mount of Olives, a nail driven through the anklebones of a man crucified in the 1st cent. CE. Evidence that Jesus was nailed rather than tied to his cross is in the request of Thomas (John 20: 25) to see ‘the mark of the nails’.
