Holy Lance
The name of the soldier who pierced Christ's side with a "lonchē" is not given in the Gospel of John, but in the oldest known references to the legend, the apocryphal Gospel of Nicodemus appended to late manuscripts of the 4th century "Acts of Pilate", the soldier is identified as a centurion and called Longinus (making the spear's Latin name "Lancea Longini").
Crucifixion
In popular depictions of the crucifixion of Jesus (possibly because in translations of the wounds are described as being "in his hands"), Jesus is shown with nails in his hands. But in Greek the word "χείρ", usually translated as "hand", could refer to the entire portion of the arm below the elbow, and to denote the "hand" as distinct from the "arm" some other word could be added, as "ἄκρην οὔτασε χεῖρα" (he wounded the end of the χείρ, i.e., "he wounded her in the hand".
