Hebrews 3:7-19

7Therefore (as the Holy Spirit saith, To day if ye will hear his voice, 8Harden not your hearts, as in the provocation, in the day of temptation in the wilderness: 9When your fathers tempted me, proved me, and saw my works forty years. 10Therefore I was grieved with that generation, and said, They do always err in their heart; and they have not known my ways. 11So I swore in my wrath, They shall not enter into my rest.)1 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 steadfast to the end; 15While it is said, To day if ye will hear his voice, harden not your hearts, as in the provocation. 16For some, when they had heard, did provoke: yet not all that came out of Egypt by Moses. 17But with whom was he grieved forty years? was it not with them that had sinned, whose bodies fell in the wilderness? 18And to whom did he swear that they should not enter into his rest, but to them that believed not? 19So we see that they could not enter in because of unbelief.
