Hebrews 3:14-19

14For we have become partakers of Christ if we hold the beginning of our confidence steadfast to the end,

15while it is said: “Today, if you will hear His voice, Do not harden your hearts as in the rebellion.”

16For who, having heard, rebelled? Indeed, was it not all who came out of Egypt, led by Moses?

17Now with whom was He angry forty years? Was it not with those who sinned, whose corpses fell in the wilderness?

18And to whom did He swear that they would not enter His rest, but to those who did not obey?

19So we see that they could not enter in because of unbelief.
