Keep the Sabbath

"If you keep your feet from breaking the Sabbath
and from doing as you please on my holy day,

if you call the Sabbath a delight and the Lord's holy day honourable,

and if you honour it by not going your own way
and not doing as you please of speaking idle words,

then you will find your joy in the Lord,

and I will cause you to ride on the heights of the land
and to feast on the inheritance of your father Jacob."

Isaiah 58: 13 - 14 (NIV)
