Amos 8:4-7

4Hear this, ye that pant after the needy, even to cause to fail the poor of the land,

5saying, 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 for deceit:

6that we may buy the poor for silver, and the needy for a pair of shoes; and that we may sell the refuse of the wheat.

7Jehovah hath sworn by the glory of Jacob, Certainly I will never forget any of their works.
