Amos 6:12

12 Shall horses run upon the rock? will one plow [there] with oxen? that ye have turned justice into gall, and the fruit of righteousness into wormwood;

Amos 6:12 In-Context

10 And when a man's uncle shall take him up, even he that burneth him, to bring out the bones out of the house, and shall say unto him that is in the innermost parts of the house, Is there yet any with thee? and he shall say, No; then shall he say, Hold thy peace; for we may not make mention of the name of Jehovah.
11 For, behold, Jehovah commandeth, and the great house shall be smitten with breaches, and the little house with clefts.
12 Shall horses run upon the rock? will one plow [there] with oxen? that ye have turned justice into gall, and the fruit of righteousness into wormwood;
13 ye that rejoice in a thing of nought, that say, Have we not taken to us horns by our own strength?
14 For, behold, I will raise up against you a nation, O house of Israel, saith Jehovah, the God of hosts; and they shall afflict you from the entrance of Hamath unto the brook of the Arabah.
