MAL 1:14

14 [I will] curse anyone who [tries to] cheat [me] by solemnly promising [to bring to me a perfect] ram from his flock [of sheep] and then brings to me one that has defects. [If anyone does that, I will punish him], because I am a great king; [I am] the Commander of the armies of angels and [people of the other] nations revere me [MTY], [but you do not]!”
