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

7 Wherefore, as the Holy Spirit says, To-day if you will hear his voice, 8 harden not your hearts as in the provocation, in the day of the trial in the wilderness, 9 where your fathers fully proved and saw my works forty years. 10 Wherefore I was displeased with that generation and said, They always err in mind, and they did not know my ways, 11 so I swore in my wrath, They shall not enter into my rest.

12 See, brothers, that there be not at any time in any one of you an evil mind of unbelief in departing from the living God; 13 but exhort one another daily, while it is called to-day, that no one of you may be hardened by the deception of sin; 14 for we have been made partakers of Christ, if we hold the beginning of the confidence firm to the end. 15 It was said, To-day if you will hear his voice, harden not your hearts as in the provocation;

16 for who having heard committed provocation? Did not all indeed who came out of Egypt with Moses? 17 And with whom was he displeased forty years? Was it not with those that sinned? whose bodies fell in the wilderness? 18 And to whom did he swear that they should not enter into his rest? was it not to them that disobeyed? 19 And we see that they could not enter in because of unbelief.
