The ass (or donkey) is an animal frequently mentioned throughout Scripture. Of the domesticated species we read of:
Asses constituted a considerable portion of wealth in ancient times (Genesis 12:16; 30:43; 1 Chr. 27:30; Job 1:3; 42:12). They were noted for their spirit and their attachment to their master (Isa. 1:3).
They are frequently spoken of as having been ridden upon, as by Abraham (Genesis 22:3), Balaam (Num. 22:21), the disobedient prophet (1 Kings 13:23), the family of Abdon the judge, seventy in number (Judg. 12:14), Zipporah (Exodus 4:20), the Shunammite (1 Sam. 25:30), etc.
Of wild asses, two species are noticed:
The wild ass was distinguished for its fleetness and its extreme shyness. In allusion to his mode of life, Ishmael is likened to a wild ass (Genesis 16:12. Here the word is simply rendered “wild” in the Authorized Version, but in the Revised Version, “wild-ass among men”).
