John Gill Commentary Acts 22:13

"came unto me, and standing by me said unto me, Brother Saul, receive thy sight. And in that very hour I looked up on him." — Acts 22:13 (ASV)

Came unto me
Being at the house of Judas, in that street of Damascus called Straight, (Acts 9:11) and stood; at the side of him, or by him, putting his hands on him:

and said unto me, brother Saul; (See Gill on Acts 9:17).

receive your sight ,
"or look up",

and the same hour I looked up upon him ;
that is, immediately, directly: for so the phrase, "that same hour", is frequently used by the Jews: the words in (Numbers 16:21) "that I may consume them in a moment", are rendered by Onkelos, "that I may consume them in an hour"; for an hour is used for a moment with them.
