Liberating the Captive: Jacob 2 and Isaiah 58

I was reading Jacob's great sermon in Jacob 2-3 the other morning and was struck by a few thematic similarities with Isaiah 58. Both of these are strong social commentaries set against the annual autumnal harvest/ingathering festival (Atonement/Tabernacles). Within this context, Jacob instructs his people to do the following:

1. Clothe the naked (Jac 2:19)
2. Feed the hungry (Jac 2:19)
3. Liberate the captive (Jac 2:19)
4. Administer relief to the sick and afflicted (Jac 2:19)

Contrast this to what Isaiah tells us:

1. Loose the bands of wickedness, to undo the heavy burdens, and to let the
oppressed go free, and that ye break every yoke (Isa 58:6)
2. Deal thy bread to the hungry (Isa 58:7)
3. Bring the poor that are cast out to thy house (Isa 58:7)
4. When thou seest the naked, that thou cover him (Isa 58:7)
5. Hide not thyself from thine own flesh (Isa 58:7)

Granted, the wording is not exact enough to show a direct dependancy (not to mention perceived Deutero- or Trito-Isaiah timeline issues), but the lists are fairly similar. There are other texts that also stress the social requirements, and many of these have a similar locus. King Benjamin's speech touches on some of the same themes (but not with as compact a list) and also shares an autumnal festival (Tabernacles) setting. And the Day of Atonement did have a strong link to the Sabbatical/Jubilee requirement to release servants from bondage.

Just a few thoughts from the comfort of my couch this morning . . .
