"The Sabbath at Home" by Silas M. Andrews is a book that says a lot about a day set aside for rest and worship.

Excerpt:

It is not proposed to dwell, in the following pages, upon the arguments that might be brought forward to prove that the Sabbath is a Divine institution, established and sanctified by the Creator on the seventh day, after all his works were finished, and renewed to Israel on the descent of the manna. Nor shall I attempt to show, from the Scriptures, that the Sabbath is a Christian institution, as well as a Jewish ordinance; or call your attention to the satisfactory reasons we have for observing, as holy time, the first day of the week, and not the seventh. No controversy will be maintained with any who object to the Sabbath as commonly acknowledged by Christians. He who sincerely seeks for instruction has no need of such argument; he already believes the Sabbath is the Lord's, and that it is to be sanctified by a holy resting all the day.
