17 Now while Peter wondered within himself what this vision which he had seen meant, behold, the men who had been sent from Cornelius had made inquiry for Simon's house, and stood before the gate.

Matthew Henry's Commentary on Acts 10:17

Commentary on Acts 10:9-18

(Read Acts 10:9-18)

The prejudices of Peter against the Gentiles, would have prevented his going to Cornelius, unless the Lord had prepared him for this service. To tell a Jew that God had directed those animals to be reckoned clean which were hitherto deemed unclean, was in effect saying, that the law of Moses was done away. Peter was soon made to know the meaning of it. God knows what services are before us, and how to prepare us; and we know the meaning of what he has taught us, when we find what occasion we have to make use of it.
