7 Therefore the holy spirit says:[ref]

‘Today if you hear his voice,

8 don’t harden your hearts as you did in the rebellion,

in the time of testing in the wilderness

9 where your ancestors tested me through trials,

although they saw my actions 10 over forty years.

That’s why I was angry with that generation and I said:

‘They’re always straying in their hearts and they don’t really know my ways.’

11 As I decided in my severe anger:

‘They will never be entering into my peace.’

12 Brothers and sisters, watch out in case any of you has an evil heart with unbelief which leads you to withdraw from the living God. 13 Instead urge yourselves on throughout each day (while it’s still called ‘today’) so that some of you won’t become hardened by the sin’s seduction 14 because we are now partakers of the messiah if we can retain until the end the assurance that we had at the beginning. 15 As it’s been said:[ref]

‘Today if you all hear his voice,

don’t harden your hearts as you did when you rebelled.’

16 Did some people heard and yet rebel? Didn’t Moses lead all of the people out of Egypt?[ref] 17 Who was he angry with for forty years? Wasn’t it the people who disobeyed God and who died there in the wilderness? 18 And who did God promise that they wouldn’t enter his rest, if it wasn’t the people who disbelieved? 19 So we can now see that they weren’t able to enter the promised land because of their unbelief.
