Hebrews 3

 ¹Wherefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our profession, Christ Jesus;

 ²Who was faithful to him that appointed him, as also Moses was faithful in all his house.

 ³For this man was counted worthy of more glory than Moses, inasmuch as he who hath builded the house hath more honour than the house.

 ⁴For every house is builded by some man; but he that built all things is God.

 ⁵And Moses verily was faithful in all his house, as a servant, for a testimony of those things which were to be spoken after;

 ⁶But 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.

 ⁷Wherefore (as the Holy Ghost saith, To day if ye will hear his voice,

 ⁸Harden not your hearts, as in the provocation, in the day of temptation in the wilderness:

 ⁹When your fathers tempted me, proved me, and saw my works forty years.

 ¹⁰Wherefore I was grieved with that generation, and said, They do alway err in their heart; and they have not known my ways.

 ¹¹So I sware in my wrath, They shall not enter into my rest.)

 ¹²Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.

 ¹³But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin.

 ¹⁴For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end;

 ¹⁵While it is said, To day if ye will hear his voice, harden not your hearts, as in the provocation.

 ¹⁶For some, when they had heard, did provoke: howbeit not all that came out of Egypt by Moses.

 ¹⁷But with whom was he grieved forty years? was it not with them that had sinned, whose carcases fell in the wilderness?

 ¹⁸And to whom sware he that they should not enter into his rest, but to them that believed not?

 ¹⁹So we see that they could not enter in because of unbelief.
