Job 39:8
Ver. 8. The range of the mountains [is] his pasture,.... It ranges about the mountains for food; it looks about for it, as the word signifies, and tries first one place and then another to get some, it having short commons there;
and he searcheth after every green thing; herb or plant, be it what it will that is green, it seeks after; and which being scarce in deserts and mountains, it searches about for and feeds upon it, wherever it can find it; grass being the peculiar food of these creatures, see Job 6:5; and which is observed by naturalists {x}.
