7 Therefore, as the Holy Spirit saith, Today if ye will hear his voice,
8 harden not your hearts, as in the provocation, in the day of temptation in the wilderness:
12 Take heed, brethren, lest there be in any of you an evil heart of unfaithfulness, to depart from the living God.
13 But exhort one another daily, while it is called Today, lest any of you be hardened through the deceitfulness of sin.
15 while it is said, Today if ye will hear his voice, harden not your hearts, as in the provocation.
