Hebrews 3:8-10

New Catholic Bible

⁸     harden not your hearts as at the rebellion,
    in the day of testing in the desert,
⁹ where your ancestors tried me and tested me
though they had seen what I could do ¹⁰     for forty years.
As a result I became angered with that generation,
    and I said, ‘Their hearts have always gone astray,
    and they do not know my ways.’
