Isaiah 58:13-14

13If thou turn back thy foot from the sabbath, [from] doing thy pleasure on my holy day, and call the sabbath a delight, the holy [day] of Jehovah, honourable; and thou honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking [idle] words; 14then shalt thou delight thyself in Jehovah, and I will cause thee to ride on the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of Jehovah hath spoken.
