Isa 58:13-14

13If 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;14then 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.
