Isaiah 58:13-14

If thou turn away thy foot from the sabbath, from doing thy pleasure on my holy day; and call the sabbath a delight, and the holy of Jehovah honorable; and shalt honor it, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words: then shalt thou delight thyself in Jehovah; and I will make thee to ride upon the high places of the earth; and I will feed thee with the heritage of Jacob thy father: for the mouth of Jehovah hath spoken it.
