Hebrews 3:9-19
3:9 “There your fathers tested me and tried me, and they saw my works for forty years.
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!’”
3:12 See to it, brothers and sisters, that none of you has an evil, unbelieving heart that forsakes the living God.
3:13 But exhort one another each day, as long as it is called “Today,” that none of you may become hardened by sin’s deception.
3:14 For we have become partners with Christ, if in fact we hold our initial confidence firm until the end.
3:15 As it says, “Oh, that today you would listen as he speaks! Do not harden your hearts as in the rebellion.”
3:16 For which ones heard and rebelled? Was it not all who came out of Egypt under Moses’ leadership?
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.
