Psalm 95:8-10

New Revised Standard Version, Anglicised

⁸     Do not harden your hearts, as at Meribah,
    as on the day at Massah in the wilderness,
⁹ when your ancestors 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 whose hearts go astray,
    and they do not regard my ways.’
