First Option - Responsorial Psalm: Deuteronomy 32:26-28, 30, 35-36

²⁶ I would have said, “I will scatter them afar, I will make the remembrance of them cease from among men,”
²⁷ had I not feared provocation by the enemy, lest their adversaries should judge amiss, lest they should say, “Our hand is triumphant, the LORD has not wrought all this.”‘
²⁸ ”For they are a nation void of counsel, and there is no understanding in them.
³⁰ How should one chase a thousand, and two put ten thousand to flight, unless their Rock had sold them, and the LORD had given them up?
³⁵ Vengeance is mine, and recompense, for the time when their foot shall slip; for the day of their calamity is at hand, and their doom comes swiftly.
³⁶ For the LORD will vindicate his people and have compassion on his servants, when he sees that their power is gone, and there is none remaining, bond or free.
