Concise Bible Dictionary:

The language of the Romans. In scripture it is only mentioned as being one of the tongues in which Pilate wrote the inscription on the cross of the Lord Jesus (Luke 23:3838And a superscription also was written over him in letters of Greek, and Latin, and Hebrew, THIS IS THE KING OF THE JEWS. (Luke 23:38); John 19:2020This title then read many of the Jews: for the place where Jesus was crucified was nigh to the city: and it was written in Hebrew, and Greek, and Latin. (John 19:20)). A number of words in the Greek of the New Testament are borrowed from the Latin. Such are σπεκουλάτωρ, “an executioner,” Lat. speculator; σοωδάριον, “a napkin,” Lat. sudarium.
