Turnus Rufus asked this question also of Rabbi Akiva, " Why is the Sabbath distinguished from other days? Rabbi Akiva replied, Why art thou distinguished from other men? The answer was, " Because it hath pleased my Master thus to honor me.* And so retorted Akiva, " It hath pleased God to honor His Sabbath.* "But what I mean,* replied the other, " was how dost thou know that it is the Sabbath-day? The reply was, The river Sambatyon proves it; the necromancer proves it; the grave of thy father proves it, for the smoke thereof rises not on the Sabbath.*
