Psalm 95:8-10

Revised Standard Version Catholic Edition

⁸     Harden not your hearts, as at Mer′ibah,
    as on the day at Massah in the wilderness,
⁹ when your fathers tested me,
    and put me to the proof, though they had seen my work.
¹⁰ For forty years I loathed that generation
    and said, “They are a people who err in heart,
    and they do not regard my ways.”
