Therefore, as the Holy Spirit says:

“Today if you hear His voice,

do not harden your hearts,

as you did in the rebellion,

in the time of testing in the wilderness,

where your fathers tried Me by testing Me,

and for forty years saw My works.

Therefore I was angry with that generation,

and I said,

‘Their hearts always go astray,

and they have not known My ways.’

So I swore on oath in My anger,

‘They shall never enter My rest.’”

See to it, brothers, that none of you has a wicked heart of unbelief that turns away from the living God. But exhort one another daily, as long as it is called today, so that none of you may be hardened by sin’s deceitfulness.” Hebrews 3:7-13
