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

⁷ Therefore, as the Holy Spirit says: "If you but hear His voice today, ⁸ You must not harden your hearts as they did in provoking me, as on the day in the desert they tested me, ⁹ Where your forefathers found I stood their test, because they saw my works for forty years, ¹⁰ So I was indignant with that generation, and I said, 'Their hearts are always going astray, and they have never come to know my ways.' ¹¹ So in my anger I took oath, 'They shall not be admitted to my rest!'"

¹² See to it, my brothers, that no wicked, unbelieving heart is found in any of you, as shown by your turning away from the ever-living God, ¹³ but day by day, as long as "Today" shall last, continue to encourage one another, so that not one of you may be hardened by sin's deceiving ways, ¹⁴ For we have become real sharers in Christ, if we keep firm to the end the faith we had at first, ¹⁵ and yet the warning continues to be spoken: "If you but hear His voice, you must not harden your hearts as they did in provoking me."

¹⁶ For who was it that heard and yet provoked Him? Was it not all who came out of Egypt led by Moses? ¹⁷ With whom was He disgusted forty years? Was it not with those who had sinned, whose carcasses fell in the desert? ¹⁸ To whom did He take oath that they should not be admitted to His rest, if it was not to those who disobeyed Him? ¹⁹ So we see that it was because of their unbelief that they could not be admitted to it.
