Isaiah 58:13-14

If you refrain from trampling the Sabbath, from pursuing your own interests on my holy day; if you call the Sabbath a delight and the holy day of the LORD honorable; if you honor it, not going your own ways, serving your own interests or pursuing your own affairs; then you shall take delight in the LORD, and I will make you ride upon the heights of the earth; I will feed you with the heritage of your ancestor Jacob, for the mouth of the LORD has spoken.
