A.T. Robertson Commentary Acts 10:45

"And they of the circumcision that believed were amazed, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Spirit." — Acts 10:45 (ASV)

They of the circumcision which believed (ο εκ περιτομης πιστο). The believing ones of the circumcision, more exactly.

Were amazed (εξεστησαν). Second aorist active indicative, intransitive, of εξιστημ. They stood out of themselves.

On the Gentiles also (κα επ τα εθνη). Or, even upon the Gentiles.

Was poured out (εκκεχυτα). Present perfect passive retained in indirect discourse of εκχεω or εκχυνω, old verb, used metaphorically of the Holy Spirit also in 2:17 (from Joe 2:28f.), Acts 2:33.
