Amos 8:5

When will the new moon be gone? ye that could wish there were nothing to interrupt your marketing, your irreligious impatience, and your eagerness after the world, look on solemn times of Divine worship as very burdensome; such was the first day of every month, and the weekly sabbath. That we may sell corn: no servile work might be done on new moons, no markets kept, or corn brought forth publicly to be sold. And the sabbath, that we may set forth wheat? they were also bound very religiously to observe the sabbath, and on that day they might not buy or sell; now they are weary of the sabbath, as of the new moon, and on the same account wish it over: here was irreligious gaping after gain. Making the ephah small; the ephah was a measure for dry things, and contained about half a bushel and one pottle English measure. Now these covetous corn-merchants measured the corn they sold by an ephah that was too little, the poor buyer had not his due. And the shekel great: they weighed the money which they received, and these rich men had no more pity and justice, than to make their shekel weight greater than the standard; so the poor were twice oppressed in the same way, had less than was their right, and paid more than they ought to pay; and thus they undid the poor, and ate him up. And falsifying the balances by deceit; deceitfully pervert the balances, that the money or shekel weighed, though of full weight, yet appeared too light on the balance, and they who paid it were forced to add more silver to it.
