Hebrews 3:7-19 - A Serious Warning Against Unbelief

⁷ Therefore as the Holy Spirit says, This day if you hear his voice, ⁸ harden not your hearts, as in the provocation, in the day of temptation in the wilderness, ⁹ whom our fathers tempted in proving me, and saw my works forty years. ¹⁰ Therefore I was provoked with this generation, and I said, They do always err in their heart: and they have not known my way, ¹¹ as I swore in my wrath, They shall not enter into my rest.

¹² See, brethren, lest at some time there shall be in some one of you an evil heart of unbelief, in turning away from the living God: ¹³ but exhort one another each day, while it is called to-day; in order that no one of you may be hardened with the deceitfulness of sin: ¹⁴ for we have been made partakers of Christ, if indeed we may hold fast the beginning of confidence firm unto the end. ¹⁵ In that it is said, This day if you hear his voice, harden not your hearts, as in the provocation:

¹⁶ for who were those, having heard, who were hardened? yea, were they not all those having come out of Egypt under Moses? ¹⁷ And with whom was he provoked forty years? was it not with those that sinned, whose carcases fell in the wilderness? ¹⁸ And to whom did he swear that they should not enter into his rest, but to those who believed not? ¹⁹ And we see that they were not able to enter in on account of their unbelief.
