Isaiah 14:6

Therefore he brought upon them the king of the Chaldees, who slew their young men with the sword in the house of their sanctuary, and had no compassion upon young man or maiden, old man, or him that stooped for age: he gave them all into his hand.

Woe to thee that spoilest, and thou wast not spoiled; and dealest treacherously, and they dealt not treacherously with thee! when thou shalt cease to spoil, thou shalt be spoiled; and when thou shalt make an end to deal treacherously, they shall deal treacherously with thee.

I beheld, and the same horn made war with the saints, and prevailed against them;

For he shall have judgment without mercy, that hath shewed no mercy; and mercy rejoiceth against judgment.
