the snorting of their horses The sneezing of his nostrils.

the neighing of their stallions The neighing of joy of his horses, and we find elsewhere that horses are called אבּירים (Jud. 5:22) by reason of the prancings, “the prancings of their mighty ones (אבּיריו),” an expression of (Nahum 3:2) “a prancing horse.” And Jonathan renders: from the sound of the steps of their mighty ones.
