Hebrews 3:8-11

8 Harden not your hearts, as in the provocation, in the day of temptation in the wilderness:

9 When your fathers tempted me, proved me, and saw my works forty years.

10 Why I was grieved with that generation, and said, They do always err in their heart; and they have not known my ways.

11 So I swore in my wrath, They shall not enter into my rest.)
