A Serious Warning Against Unbelief

7 Therefore, just as the Holy Spirit says,

“Today, if you hear his voice,

8 do not harden your hearts as in the rebellion,

in the day of testing in the wilderness,

9 where your fathers tested me by trial

and saw my works 10 for forty years.

Therefore I was angry with this generation,

and I said, ‘They always go astray in their heart,

and they do not know my ways.’

11 As I swore in my anger,

‘⌊They will never enter⌋c into my rest.’ ”d

12 Watch out, brothers, lest there be in some of you an evil, unbelieving heart, with the result that you fall away* from the living God. 13 But encourage one another ⌊day by day⌋e, as long as it is called “today,” so that ⌊none of you become hardened⌋f by the deception of sin. 14 For we have become partners of Christ, if indeed we hold fast the beginning of our commitment steadfast until the end, 15 ⌊while it is said⌋g,

“Today, if you hear his voice,

do not harden your hearts as in the rebellion.”h

16 For who, when they* heard it, were disobedient? Surely it was not all who went out from Egypt through Moses? 17 And with whom was he angry for forty years? Was it not with those who sinned, whose dead bodies fell in the wilderness? 18 And to whom did he swear they would not enter into his rest, except those who were disobedient? 19 And so we see that they were not able to enter because of unbelief.
