Jesus, that appeared unto thee in the way as thou camest, hath sent me, that thou mightest receive thy sigh t, and be filled with the Holy Ghost . Paul was baptized into Jesus' death. Scales came off his eyes. There is a vail over the eyes of understanding, the mind. The serpent from Eden blinded the minds of mankind with his lies.
Serpents have scales.
Scales fell away from Paul's eyes when his sight was restored. And those scales fell away after the three day period. The Gospel of Jesus broke through to Paul, and the truth of the death, burial and resurrection caused Paul to see the light. Jesus sent Ananias for the distinct purpose of having Paul's eyes receive sight. To help you see glory.
