12. Take heed, brethren, lest perhaps there be in any of you an evil heart of unbelief, to depart from the living God.
13. But exhort one another every day, whilst it is called to day, that none of you be hardened through the deceitfulness of sin.
14. For we are made partakers of Christ: yet so, if we hold the beginning of his substance firm unto the end.
15. While it is said, To day if you shall hear his voice, harden not your hearts, as in that provocation.
