Charles Ellicott Commentary Acts 10:23

"So he called them in and lodged them. And on the morrow he arose and went forth with them, and certain of the brethren from Joppa accompanied him." — Acts 10:23 (ASV)

Then he called them in.—As it was about noon when Peter went up to the housetop to pray, the arrival of the messengers, allowing an adequate interval for the trance and the vision, may be placed at some time in the afternoon.

Certain brothers from Joppa.—We learn from Acts 11:12 that they were six in number. They were obviously taken so that “in the mouth of two or three witnesses every word might be established” (Deuteronomy 17:6; Deuteronomy 19:15), and so that they might report to the church at Joppa what had been done by the Apostle whom they had learned to reverence.
