Hebrews 3:16-19

16For who 1provoked Him when they had heard? Indeed, 2did not all those who came out of Egypt led by Moses?

17And with whom was He angry for forty years? Was it not with those who sinned, 3whose bodies fell in the wilderness?

18And to whom did He swear 4that they would not enter His rest, but to those who were 5disobedient?

19So we see that they were not able to enter because of 6unbelief.
