Julia O'Brien has a fine post Reading Amos in Modern Tekoa, it should suggest other neat possibilities for teaching! Though as Julia shows Tekoa today offers richer possibilities than many other sites.

But as they say "the devil is in the details", and in this case I wonder about a couple of related details. Julia "point[s] out how Amos falls short of all-inclusive justice" citing Judith Sanderson in the Women’s Bible Commentary:

• "the description of Samaria’s women in 4:1-3 unfairly scapegoats women for the nation’s ills" does it? Or does this passage merely suggest that the women who enjoy the "good life" procured by oppression (cf 4:1 they at least enjoyed the drinkies) are condemned along with thoose who procured them these treats?
• Amos "failed specifically to champion the women among the poor" surely 2:7b does specifically champion a class of (poor) women (servant girls) from male abuse, and states that such abuse profanes the holy reputation of God.

I don't believe that Amos is entirely free of the taint of common social attitudes of his time (though as a male I am less likely to spot examples), doubtless the book reflects the unconscious prejudices of its writers and editors, but please limit mention of this to cases where the failure to transcend time and place are clear and unequivocal.
