How do the beasts groan! the herds of cattle are perplexed, because they have no pasture; yea, the flocks of sheep are made desolate. How do the beasts groan! - I really think that the neighing of horses, or braying of asses, is wonderfully expressed by the sound of the original: מה נאנחה בהמה mah Neenchah behemah, how do the horses neigh! how do the asses bray! בהמה behemah is a collective name for all domestic cattle, and those used in husbandry.
Cattle are perplexed - They are looking everywhere, and wandering about to find some grass, and know not which way to run.
