Amos 8:5

When — Ye that could wish there were nothing to interrupt your marketing, that look on solemn times of worship as burdensome, such was the first day of every month, and the weekly sabbath. Small — So the ephah being too little, the poor buyer had not his due. The shekel great — They weighed the money which they received, and had no more justice, than to make their shekel weight greater than the standard; so the poor were twice oppressed, had less than was their right, and paid more than they ought to pay.
