Hebrews 3:8-12

King James Version

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

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

¹² Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.
