Isaiah 58:13-14

“If you keep from desecrating the Sabbath, from doing whatever you want on My holy day; if you call the Sabbath a delight, and the holy day of the Lord honorable; if you honor it, not going your own ways, seeking your own pleasure, or talking too much; then you will delight yourself in the Lord, and I will make you ride over the heights of the land, and let you enjoy the heritage of your father Jacob.” For the mouth of the Lord has spoken.
