Psalm 81:7-9

Revised Standard Version Catholic Edition

⁷ In distress you called, and I delivered you;
    I answered you in the secret place of thunder;
    I tested you at the waters of Mer′ibah.Selah
⁸ Hear, O my people, while I admonish you!
    O Israel, if you would but listen to me!
⁹ There shall be no strange god among you;
    you shall not bow down to a foreign god.
