Woe to you, O destroyer never destroyed, O traitor never betrayed! When you have finished destroying, you will be destroyed. When you have finished betraying, you will be betrayed.
Jewish Publication Society of America Version (JPS1917) - Isaiah 33:1 >Woe to thee that spoilest, and thou wast not spoiled; and dealest treacherously, and they dealt not treacherously with thee! When thou hast ceased to spoil, thou shalt be spoiled; and when thou art weary with dealing treacherously, they shall deal treacherously with thee.
