12 Beware, brothers, lest perhaps there be in any one of you an evil heart of unbelief, in falling away from the living God; 13 but exhort one another day by day, so long as it is called "today;" lest any one of you be hardened by the deceitfulness of sin. 14 For we have become partakers of Christ, if we hold fast the beginning of our confidence firm to the end: 15 while it is said, "Today if you will hear his voice, Don't harden your hearts, as in the rebellion."
16 For who, when they heard, rebelled? No, didn't all those who came out of Egypt by Moses? 17 With whom was he displeased forty years? Wasn't it with those who sinned, whose bodies fell in the wilderness? 18 To whom did he swear that they wouldn't enter into his rest, but to those who were disobedient? 19 We see that they were not able to enter in because of unbelief.
