New King James Version

Hebrews 3:17-19 New King James Version (NKJV)

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

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

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