Amos 6:12-14
12.  Shall horses run upon the rock?  Will one plow there with oxen?  For ye have turned judgment into gall,  And the fruit of righteousness into hemlock:
13.  Ye which rejoice in a thing of nought, Which say, Have we not taken to us horns by our own strength?
14.  But, behold, I will raise up against you a nation, O house of Israel, saith the Lord the God of hosts;  And they shall afflict you from the entering in of Hemath unto the river of the wilderness.
