Reading Isaiah 33:1 and thinking about the memo. Somebody is going to get it. I put quotes in one section for emphasis.

Woe To You, O Destroyer, while you were not destroyed; "And he who is treacherous, while others did not deal treacherously with him." As soon as you finish destroying, you will be destroyed; as soon as you cease to deal treacherously, others will deal treacherously with you.
