JOY Isaiah 58:13-14

"If you keep your feet from breaking the Sabbath and from doing what you please on my holy day, if you call the Sabbath a delight and the LORD's holy day honorable, and if you honor it by not going your own way and not doing as you please or speaking idle words, then you will find your joy in the LORD, and I will cause you to ride in triumph on the heights of the land and to feast on the inheritance of your father Jacob."
