A.T. Robertson Commentary Acts 9:14

"and here he hath authority from the chief priests to bind all that call upon thy name." — Acts 9:14 (ASV)

Hath authority (εχε εξουσιαν). Probably Ananias had received letters from the Christians left in Jerusalem warning him of the coming of Saul. The protest of Ananias to Jesus against any dealing with Saul is a fine illustration of our own narrow ignorance in our rebellious moods against the will of God.
