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

7 Wherefore as the holy spirit saith, "since to-day you hear his voice, 8 harden not your hearts, as at Meriba and Massa in the desart: 9 where your fathers provoked me to give proofs of my power forty years, tho' they saw my works. 10 wherefore I was displeased with that generation, and said, they do alway err in their hearts; and they have not known my ways. 11 so I swear in my wrath, that they should not enter into my rest."

12 Take heed, brethren, lest there be in any of you such incredulity as to make you desert the living God. 13 but exhort one another daily while the day lasts, lest any of you be hardned through the deceitfulness of sin. 14 for we were receiv'd into the communion of Christ, upon condition of inviolably maintaining the hope we had at the beginning even unto the end, 15 which is imply'd by, "to-day since ye hear his voice, harden not your hearts, as at Meriba."

16 for some when they had heard his voice, did provoke him: however, not all that were brought out of Egypt by Moses did so. 17 but with whom was he displeased forty years? was it not with those that had sinned, whose carcases fell in the desert? 18 and who were they, who, he sware, should not enter into his rest, but those that did not believe? so we see that they could not enter in, 19 because of their incredulity.
