Canst thou make him afraid as a grasshopper? the glory of his nostrils is terrible.
Make ... afraid - rather, 'canst thou (as I do) make him spring as the locust х raa`ash (H7493) unites the meaning of tremble and spring up (Umbreit)]. So in Joel 2:4 the comparison is between locusts and war horses. The heads of the two are so like that the Italians call the locusts cavaletta, 'little horse.'
Nostrils - snorting furiously.
