Hebrews 3:7-19

⁷Therefore, just as the Holy Spirit says,

“Today if you hear His voice,
⁸Do not harden your hearts as when they provoked Me,
As in the day of trial in the wilderness,
⁹Where your fathers tried Me by testing Me,
And saw My works for forty years.
¹⁰“Therefore I was angry with this generation,
And said, ‘They always go astray in their heart,
And they did not know My ways’;
¹¹As I swore in My wrath,
‘They shall not enter My rest.’”

¹²Take care, brethren, that there not be in any one of you an evil, unbelieving heart that falls away from the living God. ¹³But encourage one another day after day, as long as it is still called “Today,” so that none of you will be hardened by the deceitfulness of sin. ¹⁴For we have become partakers of Christ, if we hold fast the beginning of our assurance firm until the end, ¹⁵while it is said,

“Today if you hear His voice,
Do not harden your hearts, as when they provoked Me.”

¹⁶For who provoked Him when they had heard? Indeed, did not all those who came out of Egypt led by Moses? ¹⁷And with whom was He 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 not enter His rest, but to those who were disobedient? ¹⁹So we see that they were not able to enter because of unbelief.
