7  Wherefore, even as says the Holy Spirit, To-day if ye will hear his voice, 8  harden not your hearts, as in the provocation, in the day of temptation in the wilderness; 9  where your fathers tempted me, by proving me, and saw my works forty years. 10  Wherefore I was wroth with this generation, and said, They always err in heart; and they have not known my ways; 11  so I swore in my wrath, If they shall enter into my rest. 12  See, brethren, lest there be in any one of you a wicked heart of unbelief, in turning away from the living God. 13  But encourage yourselves each day, as long as it is called To-day, that none of you be hardened by the deceitfulness of sin. 14  For we are become companions of the Christ if indeed we hold the beginning of the assurance firm to the end; 15  in that it is said, To-day if ye will hear his voice, do not harden your hearts, as in the provocation; 16  (for who was it, who, having heard, provoked? but was it not all who came out of Egypt by Moses? 17  And with whom was he wroth forty years? Was it not with those who had sinned, whose carcases fell in the wilderness? 18  And to whom sware he that they should not enter into his rest, but to those who had not hearkened to the word? 19  And we see that they could not enter in on account of unbelief;)
