“This is what the Lord says about the king of Assyria: He will never come into this city, shoot an arrow here, hold a shield in front of it, or put up dirt ramps to attack it.
Joab’s army came and attacked him in Abel (Beth Maacah). They put up a dirt ramp against the city, and it stood level with the outer wall. All the troops with Joab were trying to destroy the wall and tear it down.
The omens will indicate that he should go to the right, to Jerusalem. So he will set up his battering rams there, give the order to kill, raise a battle cry, aim the battering rams against the city gates, put up ramps, and set up blockades.
