Has anyone done a unit on ISAIAH 58:1-12?  It's all about doing God's work as the call to religious life.

Vs. 6-10...

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;

If you remove the yoke from among you,
   the pointing of the finger, the speaking of evil,
¹⁰ if you offer your food to the hungry
   and satisfy the needs of the afflicted,
then your light shall rise in the darkness
   and your gloom be like the noonday.

I'm really drawn to it, but am wondering if there is anyone who has done a unit on this or a similar text.  We did Micah 6:6-8 last year, and this one kind of expands on that same vision of doing justice I'd love to get the kids hands into.  Thanks if you have any hints or ideas!
