(9) As they went on their journey . . .--The distance from Caesarea to Joppa was about thirty Roman miles.

To pray about the sixth hour.--As in Acts 3:1, we again find St. Peter observing the Jewish hours of prayer. The "hunger" mentioned in the next verse implies that up to that time he had partaken of no food, and makes it probable that it was one of the days, the second and fifth in the week, which the Pharisees and other devout Jews observed as fasts. The flat housetop of an Eastern house was commonly used for prayer and meditation (comp. Matthew 10:27; Matthew 24:17; Luke 17:31), and in a city like Joppa, and a house like that of the tanner, was probably the only place accessible for such a purpose.

Verse 9. - Now on for on, A.V.; were for went, A.V. The house top; the quietest and most retired place in an Eastern house (comp. 1 Samuel 9:25, 26). It is not inconsistent with this that the hour-top could also be made a place of special publicity, from its height and open space (see Luke 12:3). About the sixth hour. Noon, the second of the three hours of prayer among the Jews, called "the midday prayer." The last was the ninth hour (Acts 3:1) and the first the third hour, nine in the morning (Acts 2:15). See Psalm Iv. 17.

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.On the morrow, as they went on their journey,.... From Caesarea to Joppa; Joppa is said to be six and thirty miles distant from Caesarea; so far Caesarea was from Lydda, but it seems to be further from Joppa; for according to Josephus (b), from Joppa to Antipatris were a hundred and fifty furlongs, which are almost nineteen miles, and from thence to Caesarea were twenty six miles; unless there was a nearer way by the sea shore, as there was a way by that from Caesarea to Joppa, of which the above author makes mention (c); wherefore they must either have set out the evening before, or early that morning, to get to Joppa by the sixth hour, or twelve o'clock at noon; as it seems they did, by what follows:

and drew nigh unto the city; that is, of Joppa, were but a little way distant from it:

Peter went up upon the housetop to pray; the roofs of houses in Judea were flat, and persons might walk upon them, and hither they often retired for devotion and recreation; See Gill on Matthew 10:27, Matthew 24:17, it was on the former count, namely for prayer, that Peter went up thither, and that he might, be private and alone, and undisturbed in the discharge of that duty. This being at a tanner's house, though not in his shop, brings to mind a canon of the Jews (d),

"a man may not enter into a bath, nor into a tanner's shop, near the Minchah,''

or time of prayer. Now this was about the sixth hour or twelve o'clock at noon, when Peter went up to pray; at which time the messengers from Cornelius were near the city of Joppa; this was another time of prayer used by the Jews, and is what they call the great Minchah, which began at the sixth hour and an half, and so was as is here said, about the sixth hour See Gill on Acts 3:1.
