Hebrews 3:8-19

⁸do not harden your hearts,

as you did in the rebellion,

in the day of testing in the wilderness,

⁹where your fathers tested and tried Me,

and for forty years saw My works.

¹⁰Therefore I was angry with that generation,

and I said,

‘Their hearts are always going astray,

and they have not known My ways.’

¹¹So I swore on oath in My anger,

‘They shall never enter My rest.’”

¹²See to it, brothers, that none of you has a wicked heart of unbelief that turns away from the living God.

¹³But exhort one another daily, as long as it is called today, so that none of you may be hardened by sin’s deceitfulness.

¹⁴We have come to share in Christ if we hold firmly to the end the assurance we had at first.

¹⁵As it has been said:

“Today, if you hear His voice,

do not harden your hearts,

as you did in the rebellion.”

¹⁶For who were the ones who heard and rebelled? Were they not all those Moses led out of Egypt?

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

¹⁸And to whom did He swear that they would never enter His rest? Was it not to those who disobeyed?

¹⁹So we see that it was because of their unbelief that they were unable to enter.
