Hebrews 3:7 - 13

3:7 ¶ Wherefore (as the Holy Ghost saith, To day if ye will hear his voice,
3:8 Harden not your hearts, as in the provocation, in the day of temptation in the wilderness:
3:9 When your fathers tempted me, proved me, and saw my works forty years.
3:10 Wherefore I was grieved with that generation, and said, They do alway err in their heart; and they have not known my ways.
3:11 So I sware in my wrath, They shall not enter into my rest.)
3:12 Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.
3:13 But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin.
