Charles Ellicott Commentary John 18:19

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

The high priest then asked Jesus.—Compare Notes on John 18:15. By the “high priest” is probably meant Caiaphas, though this preliminary investigation was held before Annas, and in his house, or that part of the high priest’s palace occupied by him.

Of his disciples, and of his doctrine.—This was the general subject of a series of questions. He asked, we may think, about the number of Christ’s followers; the aim they had in view; the principles which He had taught them. The object of the questions was apparently to find some technical evidence in Christ’s own words on which they may support the charges they are about to bring against Him in the legal trial before Caiaphas.
