John Gill Commentary Acts 11:4

"But Peter began, and expounded [the matter] unto them in order, saying," — Acts 11:4 (ASV)

But Peter rehearsed the matter from the beginning
Of the vision at Joppa;

and expounded it by order unto them ;
or related every particular, in a very methodical and orderly manner: he did not insist upon his authority as an apostle, and much less pretended to a primacy to the rest of the apostles; but submitted to have his case heard, examined, and judged of by the body of the brethren.
