Isaiah 54:1-2

New Revised Standard Version, Anglicised Catholic Edition

54 Sing, O barren one who did not bear;
    burst into song and shout,
    you who have not been in labour!
For the children of the desolate woman will be more
    than the children of her that is married, says the Lord.
² Enlarge the site of your tent,
    and let the curtains of your habitations be stretched out;
do not hold back; lengthen your cords
    and strengthen your stakes.
