“Today, if you hear his voice, 8 do not harden your hearts as you did in the rebellion, during the time of testing in the wilderness, 9 where your ancestors tested and tried me, though for forty years they saw what I did. 10 That is why I was angry with that generation; I said, ‘Their hearts are always going astray, and they have not known my ways.’ 11 So I declared on oath in my anger, ‘They shall never enter my rest.’ ”
12 See to it, brothers and sisters, that none of you has a sinful, unbelieving heart that turns away from the living God.13 But encourage one another daily,as long as it is called “Today,” so that none of you may be hardened by sin’s deceitfulness.14 We have come to share in Christ, if indeed we hold our original conviction firmly to the very end.15 As has just been said:
“Today, if you hear his voice, do not harden your hearts as you did in the rebellion.”
16 Who were they who heard and rebelled? Were they not all those Moses led out of Egypt?17 And with whom was he angry for forty years? Was it not with those who sinned, whose bodies perished in the wilderness?18 And to whom did God swear that they would never enter his rest if not to those who disobeyed?19 So we see that they were not able to enter, because of their unbelief.
