Hebrews 3:9

A Serious Warning Against Unbelief

⁸ harden not your hearts, as in the provocation, in the day of temptation in the wilderness: ⁹ Where your fathers tried Me by testing Me,
And saw My works for forty years.
¹⁰ Therefore, I was indignant with that generation and said, They do always err from their heart, and they have not known my ways.
