Albert Barnes Commentary Acts 22:6

"And it came to pass, that, as I made my journey, and drew nigh unto Damascus, about noon, suddenly there shone from heaven a great light round about me." — Acts 22:6 (ASV)

As I made my journey. As I was on my journey.

About noon. Acts 26:13. At mid-day. This circumstance is omitted by Luke in his account in Acts 9. Paul mentions it, as more remarkable because it occurred at mid-day, to show that he was not deluded by any meteoric or natural appearances, which usually occur at night.

See Barnes on Acts 9:3.

And also on Acts 9:4-7.

Note the terms "journey" and "journeyed."
