30:21-23Meaning
Four social reversals the land “can’t bear” The speaker says the “earth” trembles under certain conditions, meaning life feels unstable and overloaded when these things happen. Four cases are named: a servant becoming king, a fool getting full and comfortable, an unloved woman getting married, and a maid replacing her mistress. The common thread is not simply change in status, but change that tends to produce resentment, misuse of power, or turmoil in relationships.
