Isaiah 58:13,14

'If thou turn away thy foot from the Sabbath, from doing they pleasure on My Holy Day; and call the Sabbath a delight, the holy of the Lord,honourable; and shalt honour Him, not doing thine own business, nor finding thine own pleasure, nor speaking idle words: Then shalt thou delight thyself in the LORD; and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of the LORD hath spoken it.'
