A.T. Robertson Commentary John 18:19

"The high priest therefore asked Jesus of his disciples, and of his teaching." — John 18:19 (ASV)

Asked (ηρωτησεν). First aorist active indicative of ερωταω, to question, usual meaning. This was Annas making a preliminary examination of Jesus probably to see on what terms Jesus made disciples whether as a mere rabbi or as Messiah.
