He Will Punish the Speech of the Arrogant Heart
Here is the Assyrians' arrogant boasting about their power, but when they had done all that the Lord appointed, they too would be punished. This passage is all about pride. The world is centred on self but the way of Christ is self-denial. To follow Christ is better than anything this world has to offer.
