Charles H. Spurgeon on Psalms 71:4

Deliver me, O my God, out of the hand of the wicked. God is on the same side with us, and those who are our enemies are also his, for they are wicked; therefore will the Lord surely rescue his own confederates, and he will not suffer the evil to triumph over the just. He who addresses such a prayer as this to heaven, does more injury to his enemies than if he had turned a battery of Armstrongs upon them. Out of the hand of the unrighteous and cruel man. Being wicked to God, they become unrighteous towards men, and cruel in their persecutions of the godly. Two hands are here mentioned: they grasp and they crush; they strike and they would slay if God did not prevent; had they as many hands as Briarcus, the finger of God would more than match them.
