John Calvin on Acts 9:9

9. Whereas he saith, that he neither ate nor drank for the space of three days, that is to be counted a part of the miracle. For although the men of the east country endure hunger better than we, yet we do not read that any did fast three days, save only those who had want of victual, or who were constrained by some greater necessity. Therefore we gather that Paul was wonderfully afraid, “Expavefactum,” terrified. seeing that being, as it were, dead, he tasted no meat for three days.

Acts 9:10-12

10. And there was a certain disciple at Damascus, called Ananias, unto whom the Lord said in a vision, Ananias. And he said, Here am I, Lord. 11. And the Lord said unto him, Arise, and go into the way that is called Straight, and seek in the house of Judas one called Saul of Tarsus: for, behold, he prayeth. 12. And he hath seen in a vision a man, named Ananias, entering in, and laying his hand upon him that he might see.
