John Wesley on Amos 8:6

That we may buy - They would have new moons and sabbaths over, that they might go to market to buy the poor. And when these poor owed but for a very little commodity, as suppose a pair of shoes, these merciless men would take the advantage against them, and make them sell themselves to pay the debt. The refuse - This was another kind of oppression, corrupted wares, sold to those that were necessitous.
