Isaiah 58:13-14

New Revised Standard Version Catholic Edition

¹³ If you refrain from trampling the sabbath,
    from pursuing your own interests 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,
    serving your own interests, or pursuing your own affairs;^[a]
14 then you shall take delight in the Lord,
    and I will make you ride upon the heights of the earth;
I will feed you with the heritage of your ancestor Jacob,
    for the mouth of the Lord has spoken.
