“¶ On the morrow as they went on their iourney, and drew nigh vnto the citie, Peter went vp vpon the house to pray, about the sixth houre.”
1611 King James Version (KJV)
Ac 10:9 On the morrow, as they . . . drew nigh to the city. Starting in the evening, after three o'clock, they could be near Joppa, thirty miles distant, the next day, "at the sixth hour", or about twelve o'clock. Went up upon the house top to pray. To the flat roof of the house, surrounded by the usual balustrade about four feet high, a place of retirement, and often the sleeping place of the family in the warm season. Moses required balustrades to the roofs (De 22:8). See also 1Sa 9:25.
