What is "Justice"

As Aaron introduced a couple of weeks ago, we are looking at the book of Amos this summer. If you remember, Amos was just a shepherd and fig farmer who lived in a little town called Tekoa. Tekoa is in the land of Judah about 6 miles south of Bethlehem.
You might ask how this shepherd/farmer got to be in the Jewish Bible and then in our Christian Bible. That is a great question.
