Hebrews 3:7-10

Wherefore (as the Holy Ghost saith, To day if ye will hear his voice, Harden not your hearts, as in the provocation, In the day of temptation in the wilderness: When your fathers tempted me, proved me, And saw my works forty years. Wherefore I was grieved with that generation, And said, They do alway err in their heart; And they have not known my ways.
