Whom did the Lord send to place his hands on Saul so he could see again?

Answer: Ananias

The Lord sent Ananias to the house of Judas; he placed his hands on Saul, something like scales fell from his eyes, and he was baptized.

“In Damascus there was a disciple named Ananias. The Lord spoke to him in a vision, “Ananias!” “Here I am, Lord,” he answered.”— Acts 9:10 (BSB)
