12Take care, brothers, that none of you may have an evil and unfaithful heart, so as to forsake the living God. 13Encourage yourselves daily while it is still “today,” so that none of you may grow hardened by the deceit of sin. 14We have become partners of Christ if only we hold the beginning of the reality firm until the end,^f 15for it is said:

“Oh, that today you would hear his voice:

‘Harden not your hearts as at the rebellion.’”^g

16^h Who were those who rebelled when they heard? Was it not all those who came out of Egypt under Moses? 17With whom was he “provoked for forty years”? Was it not those who had sinned, whose corpses fell in the desert?ⁱ 18And to whom did he “swear that they should not enter into his rest,” if not to those who were disobedient?^j 19And we see that they could not enter for lack of faith.
