It is "To the chief musician, a psalm of David." Thus the godly are consoled by the assurance of God's sudden and retributive judgment of their enemies, who are here described not as reprobates only but as malicious against the righteous, plotting and conspiring. But suddenly God's judgment falls, others fear as they behold God's doing, and the righteous rejoice in Jehovah Who has thus appeared at length in vindication of His name.
