πνεῦμα is omitted by three important mss. followed by Laemmer and Heinichen. Burton retains the word in his text, but rejects it in a note. They are possibly correct, but I have preferred to follow the majority of the codices, thinking it quite natural that Eusebius should introduce the πνεῦμα in connection with Zacharias, who is said to have been filled with the “Spirit,” not with the “Advocate,” and thinking the omission of the word by a copyist, to whom it might seem quite superfluous after παρ€κλητον, much easier than its insertion.
