(1.) All that should be their defence and support shall be cut off by the sword. The Chaldeans had long been God's sword, wherewith he had done execution upon the sinful nations round about: but now, they being as bad as any of them, or worse, a sword is brought upon them, even upon the inhabitants of Babylon (v. 35), a sword of war; and, as it is in God's hand, sent and directed by him, it is a sword of justice. It shall be, [1.] Upon their princes; they shall fall by it, and their dignity, wealth, and power, shall not secure them. [2.] Upon their wise men, their philosophers, their statesmen, and privy-counsellors; their learning and policy shall neither secure them nor stand the public in any stead. [3.] Upon their soothsayers and astrologers, here called the liars (v. 36), for they cheated with their prognostications of peace and prosperity; the sword upon them shall make them dote, so that they shall talk like fools, and be as men that have lost all their wits. Note, God has a sword that can reach the soul and affect the mind, and bring men under spiritual plagues. [4.] Upon their mighty men. A sword shall be upon their spirits; if they are not slain, yet they shall be dismayed, and shall be no longer mighty men; for what stead will their hands stand them in when their hearts fail them? [5.] Upon their militia (v. 37): The sword shall be upon their horses and chariots; the invaders shall make themselves masters of all their warlike stores, shall seize their horses and chariots for themselves, or destroy them. The troops of other nations that were in their service shall be quite disheartened: The mingled people shall become as weak and timorous as women. [6.] Upon their exchequer: The sword shall be upon her treasures, which are the sinews of war, and they shall be robbed, and made use of by the enemy against them. See what universal destruction the sword makes when it comes with commission.
