It opens
旻天疾威,
敷于下土 'harsh and terrible is high heaven, spreading over the land below',
旻 being an old word for the sky, and blames a king who rejects good counsel and follows bad plans. Its last lines picture officials living in fear:
战战兢兢,
如临深渊,
如履薄冰 'trembling and wary, as if at the edge of a deep pool, as if treading on thin ice'.
