Charles Ellicott Commentary Acts 10:33

"Forthwith therefore I sent to thee; and thou hast well done that thou art come. Now therefore we are all here present in the sight of God, to hear all things that have been commanded thee of the Lord." — Acts 10:33 (ASV)

Thou hast well done.—The peculiar turn of the phrase, in social usage, made it the expression, not of mere approval, but of heartfelt gratitude. (Compare to St. Paul’s use of it in Philippians 4:14.)

Now therefore are we all here present.—The words imply that the circle that had gathered round Cornelius were sharers in his solicitude, ready to comply with whatever might come to them as the command of God, and yet anxiously hoping that it might not impose upon them a burden too heavy to be borne.
