35 But we seek to know clearly where He has been buried. Is His tomb made with hands? Is it, like the tombs of kings, raised above the ground? Is the Sepulchre made of stones joined together? And what is laid upon it? Tell us, O Prophets, the exact truth concerning His tomb also, where He is laid, and where we shall seek Him? And they say, Look into the solid rock which you have hewn. Look in and behold. You have in the Gospels In a sepulchre hewn in stone, which was hewn out of a rock. And what happens next? What kind of door has the sepulchre? Again another Prophet says, They cut off My life in a dungeon, and cast a stone upon Me. I, who am the Chief corner-stone, the elect, the precious, lie for a little time within a stone— I who am a stone of stumbling to the Jews, and of salvation to them who believe. The Tree of life, therefore was planted in the earth, that the earth which had been cursed might enjoy the blessing, and that the dead might be released.
