Hebrews 3:8-11

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

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

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

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