Charles H. Spurgeon on Psalms 71:13

Let them be confounded and consumed that are adversaries to my soul. It will be all this to them to see thy servant preserved; their envy and malice, when disappointed, will fill them with life consuming bitterness. The defeat of their plans shall nonplus them, they shall be confounded as they enquire the reason for their overthrow; the men they seek to destroy seem so weak, and their cause so contemptible, that they will be filled with amazement as they see them not only survive all opposition, but even surmount it. How confounded must Pharaoh have been when Israel multiplied, despite his endeavours to exterminate the race; and how consumed with rage must the Scribes and Pharisees have become when they saw the gospel spreading from land to land by the very means which they used for its destruction. Let them be covered with reproach and dishonour that seek my hurt. He would have their shame made visible to all eyes, by their wearing it in their blushes as a mantle. They would have made a laughing stock of the believer, if his God had forsaken him; therefore, let unbelief and atheism be made a public scoffing in their persons.
