6 Wild donkeys stand on the hilltops and pant for breath like jackals. Their eyes are strained looking for food, because there is none to be found.”
Darby
6 And the wild asses stand on the heights, they snuff up the wind like jackals; their eyes fail, because there is no herbage.
KJV
6 And the wild asses did stand in the high places, they snuffed up the wind like dragons; their eyes did fail, because [there was] no grass.
