Hear this, O ye that swallow up the needy, even to make the poor of the land to fail, Saying, When will the new moon be gone, that we may sell corn? And the sabbath, that we may set forth wheat, making the ephah small, and the shekel great, and falsifying the balances by deceit? That we may buy the poor for silver, and the needy for a pair of shoes; yea, and sell the refuse of the wheat? The Lord hath sworn by the excellency of Jacob, Surely I will never forget any of their works."
Amos 8:4-7
