Isaiah 58:13-14

13"If you turn back your foot from the Sabbath, from doing your pleasure on my holy day, and call the Sabbath a delight and the holy day of the Lord honorable; if you honor it, not going your own ways, or seeking your own pleasure, or talking idly;

14then you shall take delight in the Lord, and I will make you ride on the heights of the earth; I will feed you with the heritage of Jacob your father, for the mouth of the Lord has spoken."
