Ps 103:27

“Dost thou wish to see how incapable he is of hurting thee, unless permitted? "These," he saith, "wait all upon Thee, that Thou mayest give them meat in due season." And this serpent wisheth to devour, but he devoureth not whom he wisheth. ...Thou hast heard what the serpent's meat is. Thou dost not wish that God give thee to be devoured by the serpent; because not the serpent's food: i.e. forsake not the Word of God. For where it is said to the serpent, "Dust thou shalt eat," it is said to the transgressor, "Dust thou art, and unto dust thou shall return." Thou dost not wish to be the serpent's food? be not dust. How, thou repliest, shall I not be dust? If thou hast not a taste for earthly things. Hear the Apostle, that thou mayest not be dust. For the body which thou wearest is earth: but do thou refuse to be earth. What meaneth this? "Set your affection on things above, not on things on the earth." If thou dost not set thy affections on earthly things, thou art not earth: if thou art not earth, thou art not devoured by the serpent, whose appointed food is earth. The Lord giveth the serpent his food when He will, what He will: but He judgeth rightly, he cannot be deceived, He giveth him not gold for earth. "When Thou hast given it them, they gather it." ...”

“Therefore, let us all gaze upon Him, that He may feed our starving souls, He who hungered for us, who became poor though He was rich, that we might be enriched by His poverty. Just before this, we appropriately sang to Him: "All things look to You to give them their food at the proper time." If all things, then all of us. If all of us, then we too. Therefore, if we are to offer anything good in speech, it is not we who give it, but He from whom we all receive, because we all expect from Him. The time is right, let Him give, but let us do what He said to receive, that is, let us expect from Him. Let us gaze upon Him with our hearts. Just as the eyes and ears of the body are towards us, so the eyes and ears of the heart are towards Him.”
