11 and he beholdeth the heaven opened, and a certain vessel descending, as it were a great sheet, let down by four corners upon the earth: 12 wherein were all manner of fourfooted beasts and creeping things of the earth and birds of the heaven. 13 And there came a voice to him, Rise, Peter; kill and eat. 14 But Peter said, Not so, Lord; for I have never eaten anything that is common and unclean. 15 And a voice [came] unto him again the second time, What God hath cleansed, make not thou common. 16 And this was done thrice: and straightway the vessel was received up into heaven.
Matthew Henry's Commentary on Acts 10:11-16
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.
