Divine worship means the same thing where time is concerned, as the temple where space is concerned. "Temple" means... that a particular piece of ground is specially reserved, and marked off from the remainder of the land which is used either for agriculture or habitation... Similarly in divine worship a certain definite space of time is set aside from working hours and days... and like the space allotted to the temple, is not used, is withdrawn from all merely utilitarian ends.
