history
From Tang dynasty essayist Han Yu 韩愈's 《争臣论》 (On the Remonstrance Official): 彼二圣一贤者，岂不知自安佚之为乐哉？诚畏天命而悲人穷也 — those sages 'feared Heaven's mandate and grieved for human poverty'. The chengyu compresses that posture into four characters.
register
Literary and high-toned. Use sincerely for genuine compassion (writers, doctors, activists); used sarcastically it accuses someone of performative pity.
