Hebrews 3:8-10

New International Version

⁸     do not harden your hearts^(A)
as you did in the rebellion,
    during the time of testing in the wilderness,
⁹ where your ancestors tested and tried me,
    though for forty years they saw what I did.^(B)
10 That is why I was angry with that generation;
    I said, ‘Their hearts are always going astray,
    and they have not known my ways.’
