Isaiah 58:9-11 (New International Version)

 ⁹ Then you will call, and the LORD will answer;
       you will cry for help, and he will say: Here am I.
       "If you do away with the yoke of oppression,
       with the pointing finger and malicious talk,

 ¹⁰ and if you spend yourselves in behalf of the hungry
       and satisfy the needs of the oppressed,
       then your light will rise in the darkness,
       and your night will become like the noonday.

 ¹¹ The LORD will guide you always;
       he will satisfy your needs in a sun-scorched land
       and will strengthen your frame.
       You will be like a well-watered garden,
       like a spring whose waters never fail.
