Cassiodorus, on Ps 30:17

“Make thy face to shine upon thy servant; save me in thy mercy.”

“In saying, "Save me in your mercy," he denies his own merit. He constantly repeats the same things in order to teach us, nor does he ever become weary of his beloved confession, because the sweetness of the truth does not become distasteful to him. He also adds: "Lord, may I not be put to shame, for I have called upon you." Wonderful and complete is this proclamation which contains both the petition of a humble person and the indestructible strength of one who believes. So he asks not he not be put to shame by God failing to answer his prayer. But how does he believe that he is heard? "For I have called on you." Calling upon the Lord in faith is an act which finds favor rather than insulting God, for the one who calls cannot at all be deceived, assuming that he is heard by God.”
