Acts 9:17

And Ananias departed, and entered into the house; and laying his hands on him said, Brother Saul, the Lord, even Jesus, who appeared unto thee in the way which thou camest, hath sent me, that thou mayest receive thy sight, and be filled with the Holy Spirit.

Brother Saul ... By way of anticipation, Ananias, out of respect to what the Lord had revealed to him, referred to Saul as "brother," not merely a "brother Israelite" but as a brother in Christ.

Receive thy sight, and be filled with the Holy Spirit ... Saul received his sight immediately upon the imposition of Ananias' hands; and, through the same instrumentality of Ananias who commanded him to be baptized, he received the Holy Spirit. The gift in view here is the same as that promised on Pentecost to all who repented and were baptized (Acts 2:38). That Saul did not receive the Holy Spirit before his baptism is implicit in the fact that the latter was necessary to the "washing away" of his sins (Acts 22:16).
