Hebrews 3:9

A Serious Warning Against Unbelief

⁸ Harden not your hearts, as in the rebellion, in the day of testing in the wilderness: ⁹  When your fathers tested me, proved me, and saw my works forty years. ¹⁰ Therefore I was grieved with that generation, and said, They do always err in their heart; and they have not known my ways.
