Amos 1:11-12

Thus saith Jehovah: For three transgressions of Edom, yea, for four, I will not turn away the punishment thereof; because he did pursue his brother with the sword, and did cast off all pity, and his anger did tear perpetually, and he kept his wrath for ever. But I will send a fire upon Teman, and it shall devour the palaces of Bozrah.
