'Strip' in the Bible

Ephraim and Judah will [unite and] swoop down on the slopes of the Philistines toward the west;Together they will plunder the sons (Arabs) of the east.They will possess Edom and Moab,And the sons of Ammon will be subject to them.

At evening time, now look, sudden terror!Before morning the Assyrians are no more.This is the portion (fate) of those who plunder us,And the lot of those who pillage us.

Tremble, you women who are carefree;Tremble with fear, you complacent ones!Strip, undress and wear sackcloth on your waist [in grief],
