This word captures bone-deep exhaustion and hardship, appearing primarily in contexts of travel difficulty or oppression. It describes Israel's weariness in Egypt and the wilderness, the exhaustion of difficult journeys and hard labor. Malachi uses it for the priests' complaint that temple service is wearisome. The term goes beyond simple tiredness to encompass the grinding fatigue of sustained hardship, the kind of exhaustion that comes from relentless difficulty without relief.
