Hebrews 3

Jesus Our Apostle and High Priest

Therefore, holy brothers, who share in [the] heavenly calling, set your focus on Jesus, the apostle and high priest whom we confess. He was faithful to the [One who] appointed Him, just as Moses [was faithful] in all [God’s] house. For [Jesus] has been counted worthy of greater glory than Moses, just as the builder [of a house] has greater honor than the house [itself] . And every house is built by someone, but God [is] the builder of everything. Now Moses [was] faithful as a servant in all [God’s] house,
Numbers 12:7
testifying to what would be spoken later.
But Christ [is faithful] as [the] Son over [God’s] house. [And] we are [His] house, if we hold firmly
NE, WH, BYZ, and TR include firmly to the end
to [our] confidence and the hope [of which] we boast.

Do Not Harden Your Hearts

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 tested [and] tried [Me] , and for forty years saw My works. 10  Therefore I was angry with that generation, and I said, ‘Their hearts always go astray, and they have not known My ways.’ 11  So I swore on oath in My anger, ‘vvv They shall never enter My rest.’”
Psalm 95:7-11

The Peril of Unbelief

12  See to it, brothers, [that] [none] of you has a wicked heart of unbelief that turns away from [the] living God. 13  But exhort 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 we hold firmly to [the] end the assurance [we had] at first. 15  As it has been said: “Today, if you hear His voice, {do} not harden your hearts, as [you did] in the rebellion.”
Psalm 95:7,8
16  For who were the ones who heard [and] rebelled? [Were they] not all those Moses led out of Egypt? 17  And with whom was [God] angry for forty years? [Was it] not with those who sinned, whose bodies fell in the wilderness? 18  And to whom did He swear [that they] would never enter His rest? [Was it] not to those who disobeyed? 19  [So] we see that [it was] because of [their] unbelief that they were unable to enter.
