St Augustine of AfricaAbout His resurrection also the oracles of the Psalms are by no means silent.

For what else is it that is sung in His person in the 3rd Psalm, “I laid me down and took a sleep, and I awaked, for the Lord shall sustain me” (Ps. 3:5)?

Is anyone so foolish as to believe that the prophet chose to point it out to us as something great that He had slept and risen up, unless that sleep had been death, and that awaking the resurrection, which were fittingly prophesied concerning Christ?

For in the 40th Psalm also it is shown much more clearly, where in the person of the Mediator, in the usual way, things are narrated as if past which were prophesied as yet to come, since these things which were yet to come were in the predestination and foreknowledge of God as if they were done, because they were certain.

[…] The 15th Psalm also cries, “Therefore my heart is jocund, and my tongue hath exulted; moreover, my flesh also shall rest in hope:  for Thou wilt not leave my soul in hell; neither wilt Thou give Thine Holy One to see corruption” (Ps. 15:9-10).

Who but He that rose again the third day could say his flesh had rested in this hope; that His soul, not being left in hell, but speedily returning to it, should revive it, that it should not be corrupted as corpses are wont to be, which they can in no wise say of David the prophet and king?

The 67th Psalm also cries out, “Our God is the God of Salvation:  even of the Lord the exit was by death” (Ps. 67:20). What could be more openly said?  For the God of salvation is the Lord Jesus, which is interpreted Saviour, or Healing One.

For this reason this name was given, when it was said before He was born of the virgin:  “Thou shall bring forth a Son, and shalt call His name Jesus; for He shall save His people from their sins” (Matt. 1:21).

Because His blood was shed for the remission of their sins, it behoved Him to have no other exit from this life than death.  Therefore, when it had been said, “Our God is the God of salvation,” immediately it was added, “Even of the Lord the exit was by death,” in order to show that we were to be saved by His dying.

But that saying is marvellous, “Even of the Lord,” as if it was said: such is that life of mortals, that not even the Lord Himself could go out of it otherwise save through death.
