Hebrews 3:10-11
3:10 “Therefore, I became provoked at that generation and said, ‘Their hearts are always wandering and they have not known my ways.’
3:11 “As I swore in my anger, ‘They will never enter my rest!’”
Hebrews 3:17-19
3:17 And against whom was God
provoked for forty years? Was it not those who sinned,
whose dead bodies fell in the wilderness?
3:18 And to whom did he swear they would never enter into his rest, except those who were disobedient?
3:19 So
we see that they could not enter because of unbelief.
