4 First, then, in the 11th Psalm He says, For the misery of the poor, and the sighing of the needy, now will I arise, says the Lord. But this passage still remains doubtful with some: for He often rises up also in anger, to take vengeance upon His enemies.
Come then to the 15th Psalm, which says distinctly: Preserve Me, O Lord, for in You have I put my trust: and after this, their assemblies of blood will I not join, nor make mention of their names between my lips; since they have refused me, and chosen Cæsar as their king: and also the next words, I foresaw the Lord alway before Me, because He is at My right hand, that I may not be moved: and soon after Yea and even until night my reins chastened me. And after this He says most plainly, For You will not leave My soul in hell ; neither will You allow Your Holy One to see corruption. He said not, neither will You allow Your Holy One to see death, since then He would not have died; but corruption, says He, I see not, and shall not abide in death. You have made known to Me the ways of life. Behold here is plainly preached a life after death. Come also to the 29th Psalm, I will extol You, O Lord, for You have lifted Me up, and hast not made My foes to rejoice over Me. What is it that took place? Were you rescued from enemies, or were you released when about to be smitten? He says himself most plainly, O Lord, You have brought up My soul from hell. There he says, You will not leave, prophetically: and here he speaks of that which is to take place as having taken place, You have brought up. You have saved Me from them that go down into the pit. At what time shall the event occur? Weeping shall continue for the evening, and joy comes in the morning: for in the evening was the sorrow of the disciplines, and in the morning the joy of the resurrection.
