And the following words of the Psalm: 'But You, O Lord, remove not Your help far from me; attend to my succour; deliver my soul from the sword, and my only-begotten from the power of the dog; save me from the lion's mouth, and my lowliness from the horns of the unicorns'—were likewise teaching and foretelling of the things that belonged to Him and were to befall Him. For that He was the only-begotten of the Father of all things, begotten of Him in a peculiar manner as Word and Power, and afterward becoming man through the virgin, as we have learned from the memoirs, I have already shown.
And that being crucified He died, He likewise foretold. For the saying 'Deliver my soul from the sword, and my only-begotten from the power of the dog; save me from the lion's mouth, and my lowliness from the horns of the unicorns,' likewise signifies by what suffering He was about to die, that is, by being crucified. For that the 'horns of the unicorns' is the figure of the cross alone, I have already expounded to you.
And His asking that His soul be saved from the sword and the lion's mouth and the power of the dog was a request that no one might gain mastery over His soul; so that, when we come to the departure from this life, we may ask the same things of God, who is able to turn away every shameless evil angel from laying hold of our soul.
And that souls survive, I have shown to you from the fact that the soul of Samuel was called up by the witch, as Saul desired. And it appears also that all the souls of such righteous men and prophets fell under the power of such powers as is indeed acknowledged from the very facts in the case of that witch.
Whence also God teaches us, even through His Son, by all means to strive to become righteous, and at our departure to ask that our souls may not fall under any such power. For also, when He gave up the spirit on the cross, He said, 'Father, into Your hands I commit my spirit,' as I have learned this too from the memoirs.
For indeed, urging His disciples to surpass the conduct of the Pharisees, and otherwise to know that they would not be saved, He is written in the memoirs to have said these things: 'Unless your righteousness exceeds that of the scribes and Pharisees, you shall in no wise enter into the kingdom of the heavens.'
