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

⁷ Therefore, as the Holy Spirit says, "Today if you will hear His voice, ⁸ do not harden your hearts, as in the provocation, in the day of temptation in the wilderness, ⁹ when your fathers tempted Me, proved Me, and saw My works forty years. ¹⁰ Therefore I was grieved with that generation and said, They always err in their heart, and they have not known My ways. ¹¹ So I swore in My wrath, They shall not enter into My rest."

¹² Take heed, brothers, lest there be in any of you an evil heart of unbelief, in departing from the living God. ¹³ But exhort one another daily, while it is called today, lest any of you be hardened through the deceitfulness of sin. ¹⁴ For we are made partakers of Christ, if we hold the beginning of our confidence steadfast to the end, ¹⁵ while it is said, "Today if you will hear His voice, harden not your hearts, as in the provocation."

¹⁶ For some, when they had heard, did provoke; however, not all who came out of Egypt by Moses. ¹⁷ But with whom was He grieved forty years? Was it not with those who had sinned, whose carcasses fell in the wilderness? ¹⁸ And to whom did He swear that they should not enter into His rest, but to those who did not believe? ¹⁹ So we see that they could not enter in because of unbelief.
