Hebrews 3:16-19

16For which ones heard and rebelled? Was it not all who came out of Egypt under Moses’ leadership?

17And against whom was God provoked for forty years? Was it not those who sinned, whose dead bodies fell in the wilderness?

18And to whom did he swear they would never enter into his rest, except those who were disobedient?

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