A.T. Robertson Commentary Acts 10:27

"And as he talked with him, he went in, and findeth many come together:" — Acts 10:27 (ASV)

As he talked with him (συνομιλων αυτω). Present active participle of συνομιλεω, rare compound and here alone in the N.T., with associative instrumental case. The uncompounded verb is common enough though in the N.T. only in Lu 24:14 which see and Ac 20:11; 24:26.

Findeth (ευρισκε). Vivid historical present indicative active.

Come together (συνεληλυθοτας). Second perfect active participle of συνερχομα. It was an expectant group of Gentiles eager for Peter's interpretation of the vision of Cornelius.
