Hebrews Chapter 3 Verse 15For some, when they had heard, did provoke: howbeit not all that came out of Egypt by Moses.

But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.

Wherefore (as the Holy Ghost saith, To day if ye will hear his voice,

Harden not your hearts, as in the provocation, in the day of temptation in the wilderness:

When your fathers tempted me, proved me, and saw my works forty years.

Wherefore I was grieved with that generation, and said, They do alway err in [their] heart; and they have not known my ways.

So I sware in my wrath, They shall not enter into my rest.)

Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.

But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin.

For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end;

While it is said, To day if ye will hear his voice, harden not your hearts, as in the provocation.

But with whom was he grieved forty years? [was it] not with them that had sinned, whose carcases fell in the wilderness?

And to whom sware he that they should not enter into his rest, but to them that believed not?

So we see that they could not enter in because of unbelief.

Let us therefore fear, lest, a promise being left [us] of entering into his rest, any of you should seem to come short of it.

For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard [it].

For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world.

For he spake in a certain place of the seventh [day] on this wise, And God did rest the seventh day from all his works.

And in this [place] again, If they shall enter into my rest.

Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief:

Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts.
