Hastings' Dictionary of the Bible (1898)
DRAG'ON. This word, in the Bible, has at least three meanings. Very commonly, where it occurs in connection with ostriches, owls, deserts, and ruins, it denotes the jackal, whose characteristics are unmistakably indicated, such as his "wailing" and "snuffing up the wind." So in Job 30:29; Ps 44:19; Jer 9:11, in all which passages solitude and desolation are illustrated. Mic 1:8. In some passages it denotes monsters of the deep or huge
land-reptiles, as in Deut 32:33; Ps 91:13. The figurative use of this term, as in Ps 74:13; Eze 29:3; Rev 12:3 and Rev 20:2, is sufficiently obvious.
