Job 30:29

29. Brother See note, Job 17:14. By his cry he has become a brother to dragons, (Hebrew, tannim,) rather, jackals, whose howl is a wailing like that of a child. It begins with the setting of the sun and continues all night. Dr. Thomson speaks of a concert of jackals as the most frightful noise he ever heard. ( Land and Book, 1:113.)

Owls Literally, daughters of the ostrich. The cry of the ostrich is hideous, sometimes resembling the roar of a lion; then again, the hoarse voice of the bull. “I have often heard them groan as if they were in the greatest agonies.” Dr. Shaw, (comp. Micah 1:8.) Shakspeare borrows the imagery of this verse,

though I go alone,

Like to a lonely dragon, that his fen Makes feared.

Coriolanus, iv, sc. 1.
