Heb 3:8-9 : 8 Harden not your hearts, as in the prouocation, according to the day of the tentation in the wildernes,
9 Where your fathers tempted me, prooued me, and sawe my workes fourtie yeeres long.
10 Wherefore I was grieued with that generation, and sayde, They erre euer in their heart, neither haue they knowen my wayes.
11 Therefore I sware in my wrath, If they shall enter into my rest.
12 Take heede, brethren, least at any time there be in any of you an euill heart, and vnfaithfull, to depart away from the liuing God.
13 But exhort one another dayly, while it is called to day, lest any of you be hardened through the deceitfulnes of sinne.
14 For we are made partakers of Christ, if we keepe sure vnto the ende that beginning, wherewith we are vpholden,
15 So long as it is sayd, To day if ye heare his voyce, harden not your hearts, as in the prouocation.
16 For some when they heard, prouoked him to anger: howbeit, not all that came out of Egypt by Moses.
17 But with whome was he displeased fourtie yeeres? Was hee not displeased with them that sinned, whose carkeises fell in the wildernes?
18 And to whom sware he that they should not enter into his rest, but vnto them that obeyed not?
19 So we see that they could not enter in, because of vnbeliefe.
