7Therefore, even as the Holy Spirit says, "Today if you will hear his voice,
8Don`t harden your hearts, as in the provocation, Like as in the day of the trial in the wilderness,
12Beware, brothers, lest perhaps there will 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 "today;" lest any one of you be hardened by the deceitfulness of sin. 14For we have become partakers of Christ, if we hold fast the beginning of our confidence firm to the end: 15while it is said, "Today if you will hear his voice, Don`t harden your hearts, as in the provocation."
16For who, when they heard, did provoke? No, didn`t all those who came out of Egypt by Moses?
