Isaiah 58:13-14

13 If you turn away your foot from the Sabbath, from doing your pleasure on my holy day; and call the Sabbath a delight, and the holy of Yahweh honorable; and shall honor it, not doing your own ways, nor finding your own pleasure, nor speaking your own words:  14 then shall you delight yourself in Yahweh; and I will make you to ride on the high places of the earth; and I will feed you with the heritage of Jacob your father: for the mouth of Yahweh has spoken it.
