This passage from Iasaih says it all…

Is not this the fast that I choose:
to loose the bonds of injustice,
to undo the thongs of the yoke,
to let the oppressed go free,
and to break every yoke?
⁷ Is it not to share your bread with the hungry,
and bring the homeless poor into your house;
when you see the naked, to cover them,
and not to hide yourself from your own kin?
⁸ Then your light shall break forth like the dawn,
and your healing shall spring up quickly;
your vindicator^* shall go before you,
the glory of the Lord shall be your rearguard.
⁹ Then you shall call, and the Lord will answer;
you shall cry for help, and he will say, Here I am. (Isaiah 58: 6-9)
