II. The design of the king of Babylon against them and the descent he make upon them: He has taken counsel against you and has conceived a purpose against you, v. 30. That proud man resolves it shall never be said that he, who had conquered so many strong cities, will leave those unconquered that dwell in tents. It was strange that that eagle should stoop to catch these flies, that so great a prince should play at such small game; but all is fish that comes to the ambitious covetous man's net. Note, It will not always secure men from suffering wrong to be able to say that they have done no wrong; not to have given offence will not be a defence against such men as Nebuchadnezzar. Yet, how unrighteous soever he was in doing it, God was righteous in directing it. These people had lived inoffensively among their neighbours, as many do, who yet, like them, are guilty before God; and it was to punish them for their offences against him that God said (v. 28): Arise, go up to Kedar, and spoil the men of the east. They will do it to gratify their own covetousness and ambition, but God orders it for the correcting of an unthankful people, and for warning to a careless world to expect trouble when they seem to be most safe. God says to the Chaldeans (v. 31): "Arise, get up to the wealthy nation that dwells without care; go and give them an alarm, that none may imagine their mountain stands so strong that it cannot be moved."
