'Wild ass' in the Bible

Doth the wild ass roar when he hath grass? Or crieth the ox, when he hath fodder enough?

A vain body exalteth himself, and man, newborn, is like a wild ass's colt.

Who letteth the wild ass go free, or who looseth the bonds of the mule?

and thy wantonness is like a wild Ass, that useth the wilderness, and that snuffeth and bloweth at his will. Who can tame thee? All they that seek thee, shall not fail, but find thee in thy own uncleanness.

Since they went up to the Assyrians, they are become like a wild ass in the desert. Ephraim giveth rewards to get lovers.
