2. He will reckon with his and their enemies, v. 5, 6. When the Assyrian army promises itself a plentiful harvest in the taking of Jerusalem and the plundering of that rich city, when the bud of that project is perfect, before the harvest is gathered in, while the sour grape of their enmity to Hezekiah and his people is ripening in the flower and the design is just ready to be put in execution, God shall destroy that army as easily as the husbandman cuts off the sprigs of the vine with pruning hooks, or because the grape is sour and good for nothing, and will not be cured, takes away and cuts down the branches. This seems to point at the overthrow of the Assyrian army by a destroying angel, when the dead bodies of the soldiers were scattered like the branches and sprigs of a wild vine, which the husbandman has cut to pieces. And they shall be left to the fowls of the mountains, and the beasts of the earth, to prey upon, both winter and summer; for as God's people are protected all seasons of the year, both in cold and heat (v. 4), so their enemies are at all seasons exposed; birds and beasts of prey shall both summer and winter upon them, till they are quite ruined.
