Isaiah 58:13-14

If you turn your foot from breaking the Sabbath, from doing as you please on My holy day, if you call the Sabbath a delight, and the LORD’s holy day honorable, if you honor it by not going your own way or seeking your own pleasure or speaking idle words, then you will delight yourself in the LORD, and I will make you ride on the heights of the land and feed you with the heritage of your father Jacob.” For the mouth of the LORD has spoken.
