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

The antiphon of the Introït is taken from Psalm 26, which well reflects the sentiments of the Church in this period of combat and danger: "The Lord is my light and my salvation: whom shall I fear? The Lord is the protector of my life: of whom shall I be afraid? My enemies that trouble me have themselves been weakened and have fallen."

The Gradual respond, taken from Psalm 78, is the same as the one for Ember Saturday in December, after the first lesson: "Forgive us our sins, O Lord, lest the Gentiles should at any time say: Where is their God? Help us, O God, our Savior; and for the honor of Thy name, O Lord, deliver us."

The versicle of the Alleluia is taken from Psalm 9, which is alphabetic. God has prepared his throne for judgment. He is the refuge of the poor in tribulation.

The versicle for the Offertory, taken from Psalm 12, is the same as that of the Saturday before the third Sunday of Lent: "Enlighten my eyes, that I never sleep in death; lest at any time my enemy say: I have prevailed against him."

The antiphon for the Communion is taken from Psalm 17. In the midst of the continual fluctuations of this world, and the instability of things, God alone does not change, and always remains the very faithful friend and unshakable stronghold of all those who confide in Him.
