The snorting of his horses was heard from Dan: the whole land trembled at the sound of the neighing of his strong ones; for they are come, and have devoured the land, and all that is in it; the city, and those that dwell therein.
His horses - the Chaldean's.
Was heard - the prophetic past for the future.
From Dan - bordering on Phenicia. This was to be Nebuchadnezzar's route in invading Israel: the cavalry in advance of the infantry would scour the country.
Strong ones - a poetical phrase for steeds, special to Jeremiah (Jeremiah 47:3, "The stamping of the hoofs of his strong (horses);" cf. Jeremiah 4:13; Jeremiah 4:29; Jeremiah 6:23).
