“Now while Peter doubted in himself what this vision which he had seen should mean, behold, the men which were sent from Cornelius had made enquiry for Simon's house, and stood before the gate,”
King James Version (KJV)
10:17 While Peter doubted in himself, behold the men - Frequently the things which befall us within and from without at the same time, are a key to each other. The things which thus concur and agree together, ought to be diligently attended to.
Ac 10:17-23 While Peter doubted. Doubted, not what the Lord had said, but what was the special object. It was while he was thinking over the matter that the messenger came. The Spirit told him their purpose and what he must do. He, therefore, called in the men, took care of them till the next day, and then returned with them. Six Jewish brethren from Joppa went with him (Ac 11:12).
