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.) 12Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.13But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin. 14For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end; 15While it is said, To day if ye will hear his voice, harden not your hearts, as in the provocation.
