Charles H. Spurgeon on Psalms 119:84

When wilt thou execute judgment, etc. This is an ordinary prayer, not against any certain persons, but rather generally against God's enemies and their evil courses. For the Lord executeth judgment upon his children for their conversion, as Paul (Acts 9:0), and upon the wicked for their confusion. He prayeth against them that belonged not to God, and yet not so much against their persons as their evil causes; and no otherwise against their persons than as they are joined with the evil causes. Thus we may pray for the confusion of God's enemies; otherwise we cannot. R. Greenham.
