Hebrews 3

To-day if ye shall hear his voice,

⁸Harden not your hearts, as in the provocation,

Like as in the day of the trial in the wilderness,

⁹Where your fathers tried me by proving me,

And saw my works forty years.

¹⁰Wherefore I was displeased with this generation,

And said, They do always err in their heart:

But they did not know my ways;

¹¹As I sware in my wrath,

They shall not enter into my rest.

¹²Take heed, brethren, lest haply there shall be in any one of you an evil heart of unbelief, in falling away from the living God: ¹³but exhort one another day by day, so long as it is called To-day; lest any one of you be hardened by the deceitfulness of sin: ¹⁴for we are become partakers of Christ, if we hold fast the beginning of our confidence firm unto the end: ¹⁵while it is said,

To-day if ye shall hear his voice,

Harden not your hearts, as in the provocation.

¹⁶For who, when they heard, did provoke? nay, did not all they that came out of Egypt by Moses? ¹⁷And with whom was he displeased forty years? was it not with them that sinned, whose bodies fell in the wilderness? ¹⁸And to whom sware he that they should not enter into his rest, but to them that were disobedient? ¹⁹And we see that they were not able to enter in because of unbelief.
