3 My God, I will cry unto You in the daytime, and You will not hear. My God, I will cry unto You in the prosperous circumstances of this life, that they be not changed; and You will not hear, because I shall cry unto You in the words of my sins. “And in the night-season, and not to my folly.” And so in the adversities of this life will I cry to You for prosperity; and in like manner You will not hear. And this You do not to my folly, but rather that I may have wisdom to know what You would have me cry for, not with the words of sins out of longing for life temporal, but with the words of turning to You for life eternal.
4. “But You dwell in the holy place, O Thou praise of Israel”. But You dwell in the holy place, and therefore will not hear the unclean words of sins. The “praise” of him that sees You; not of him who has sought his own praise in tasting of the forbidden fruit, that on the opening of his bodily eyes he should endeavour to hide himself from Your sight.
5. “Our Fathers hoped in You.” All the righteous, namely, who sought not their own praise, but Yours. “They hoped in You, and You delivered them”.
6. “They cried unto You, and were saved.” They cried unto You, not in the words of sins, from which salvation is far; and therefore were they saved. “They hoped in You, and were not confounded”. “They hoped in You,” and their hope did not deceive them. For they placed it not in themselves.
7. “But I am a worm, and no man”. But I, speaking now not in the person of Adam, but I in My own person, Jesus Christ, was born without human generation in the flesh, that I might be as man beyond men; that so at least human pride might deign to imitate My humility. “The scorn of men, and outcast of the people.” In which humility I was made the scorn of men, so as that it should be said, as a reproachful railing, “Be His disciple:” and that the people despise Me.
8. “All that saw Me laughed Me to scorn”. All that saw Me derided Me. “And spoke with the lips, and shook the head.” And they spoke, not with the heart, but with the lips.
