Isaiah 58:9-10

9Then 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,

10and 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.
