Matthew Henry's Complete Bible Commentary
Verse 84
Here, I. David prays against the instruments of his troubles, that God would make haste to execute judgment on those that persecuted him. He prays not for power to avenge himself (he bore no malice to any), but that God would take to himself the vengeance that belonged to him, and would repay (Romans 12:19), as the God that sits in the throne judging right. There is a day coming, and a great and terrible day it will be, when God will execute judgment on all the proud persecutors of his people, tribulation to those that troubled them; Enoch foretold it (Jude 1:14), whose prophecy perhaps David here had an eye to; and that day we are to look for and pray for the hastening of. Come, Lord Jesus, come quickly. 2. He pleads the long continuance of his trouble: “How many are the days of thy servant? The days of my life are but few” (so some); “therefore let them not all be miserable, and therefore make haste to appear for me against my enemies, before I go hence and shall be seen no more.” Or rather, “The days of my affliction are many; thou seest, Lord, how many they be; when wilt thou return in mercy to me? Sometimes, for the elect’s sake, the days of trouble are shortened. O let the days of my trouble be shortened; I am thy servant; and therefore, as the eyes of a servant are to the hand of his master, so are mine to thee, until thou have mercy on me.” MHBCC 598.76
