[7] Wherefore (as the Holy Ghost saith, To day if ye will hear his voice, [8] Harden not hearts, as in the provocation, in the day of temptation in the wilderness: [9] When fathers tempted and works forty years. [10] Wherefore I was grieved generation, and said, alway err in their heart; and they not known ways. [11] So I sware in wrath, not enter into rest.) [12] Take heed, brethren, in any an evil heart of unbelief, in departing from the living God.
