Isaiah 58:6-8

6"Is not this the fast that I choose: to loose the bonds of wickedness, to undo the straps of the yoke, to let the oppressed go free, and to break every yoke?

7Is it not to share your bread with the hungry and bring the homeless poor into your house; when you see the naked, to cover him, and not to hide yourself from your own flesh?

8Then shall your light break forth like the dawn, and your healing shall spring up speedily; your righteousness shall go before you; the glory of the Lord shall be your rear guard.
