Acts 10:23

Called he. For Peter to call these Gentiles into the house was to take a first step toward laying aside scruples that the Jews felt toward non-Jews.

On the morrow. Since it was about noon that Peter went up to the housetop to pray, the arrival of the messengers following his vision must have been in the early afternoon. Because it was already too late to reach Caesarea, some 30 miles away, yet that day, Peter did not set out until the following day. Also the messengers doubtless needed to rest from their journey to Joppa.

Certain brethren. These men were, of course, Jewish Christian, and according to Acts 11:12, they were six in number. Doubtless Peter remembered Christ’s words: “In the mouth of two or three witnesses every word may be established.” He wished them to report to the church whatever he did. The usefulness of their testimony later in Jerusalem is implied in Acts 11:12. No doubt Peter informed them of his vision and of the message that Cornelius’ servants had brought. The good reputation of Cornelius would have weight with them and make them ready to go with Peter.
