Summary of comments of this office by Dom Schuster, in his work L'année liturgique.

The Introït is taken from Psalm 30: "Be Thou unto me a God, a protector, and a place of refuge, to save me: for Thou art my strength, and my refuge: and for Thy name's sake Thou wilt be my leader, and wilt nourish me."

Today, the Gradual responsory is taken from Psalm 76; it is less sad than that of the two previous stations, because the soul is already beginning to see its victory victory thanks to its hope in the help of the Lord: "Thou art the God that alone dost wonders: Thou hast made Thy power known among the nations. With Thy arm Thou hast redeemed Thy people, the children of Israel and of Joseph."

The Tract is a beautiful hymn of thanksgiving to God for his divine attributes of Father and Shepherd of his people. "Sing joyfully to God all the earth: serve ye the Lord with gladness. Come in before His presence with exceeding great joy: know ye that the Lord is God. He made us, and not we ourselves: but we are His people, and the sheep of His pasture."

The antiphon for the Offertory psalm (Ps. 118) blesses God for giving to the psalmist the grace to pronounce fearlessly all his judgements even before the powerful men of the world and the impious. And at the same time, it begs him to continue to instruct him interiorly concerning his commandments.

The Communion antiphon comes from Psalm 77 and its litteral meaning is about the Hebrews who, in the desert, were miraculously fed with the flesh of the quails they had desired. But it also applies to the Eucharist, of which the miracles of the Old Law were symbols or prophetic figures: "They did eat, and were filled exceedingly, and the Lord gave them their desire: they were not defrauded of that which they craved."
