The prophet continues the metaphor; this lion is the king of Assyria.
Did tear in pieces; formerly did fall upon his neighbour nations, broke their strength, and robbed their treasuries and store-houses, and broke them in pieces.
For his whelps; the young brood of the Assyrian royal family.
Lionesses; queens, concubines, or ladies in the Assyrian court.
Filled his holes; his treasuries, magazines, and royal seats, called dens in a decorum to the speech he had used.
And his dens; ingeminating what was before spoken.
With ravin; spoils which his ravenous mind and hand could lay hold on; all was prey that he could take.
