Psalms 3:5

The words, "I slept, and took rest; and rose, for the Lord will take me up," [Psalm 3:5] lead us to believe that this Psalm is to be understood as in the Person of Christ; for they sound more applicable to the Passion and Resurrection of our Lord, than to that history in which David's flight is described from the face of his rebellious son. And, since it is written of Christ's disciples, "The sons of the bridegroom fast not as long as the bridegroom is with them;" [Matthew 9:15] it is no wonder if by his undutiful son be here meant that undutiful disciple who betrayed Him. From whose face although it may be understood historically that He fled, when on his departure He withdrew with the rest to the mountain; yet in a spiritual sense, when the Son of God, that is the Power and Wisdom of God, abandoned the mind of Judas; when the Devil wholly occupied him; as it is written, "The Devil entered into his heart," [John 13:27] may it be well understood that Christ fled from his face; not that Christ gave place to the Devil, but that on Christ's departure the Devil took possession. Which departure, I suppose, is called a flight in this Psalm, because of its quickness; which is indicated also by the word of our Lord, saying, "That you do, do quickly." [John 13:27] So even in common conversation we say of anything that does not come to mind, it has fled from me; and of a man of much learning we say, nothing flies from him. Wherefore truth fled from the mind of Judas, when it ceased to enlighten him. But Absalom, as some interpret, in the Latin tongue signifies, Patris pax, a father's peace. And it may seem strange, whether in the history of the kings, when Absalom carried on war against his father; or in the history of the New Testament, when Judas was the betrayer of our Lord; how "father's peace" can be understood. But both in the former place they who read carefully, see that David in that war was at peace with his son, who even with sore grief lamented his death, saying, "O Absalom, my son, would God I had died for you!" [2 Samuel 18:33] And in the history of the New Testament by that so great and so wonderful forbearance of our Lord; in that He bore so long with him as if good, when He was not ignorant of his thoughts; in that He admitted him to the Supper in which He committed and delivered to His disciples the figure of His Body and Blood; finally, in that He received the kiss of peace at the very time of His betrayal; it is easily understood how Christ showed peace to His betrayer, although he was laid waste by the intestine war of so abominable a device. And therefore is Absalom called "father's peace," because his father had the peace, which he had not.

The prophetic psalms are by no means silent on the subject of [Christ's] resurrection.… What other meaning can be taken from these words in Psalm 3, sung in the person of Christ?… For, unless one sees in this sleep the death, and in this awaking the resurrection of Christ thus prophesied, one is reduced to the silly supposition that the prophet wished to communicate to us the really remarkable news that he himself fell asleep and later on woke up!
