Hebrews 3:15

13But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin.

14For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end;

15While it is said, To day if ye will hear his voice, harden not your hearts, as in the provocation.

16For some, when they had heard, did provoke: howbeit not all that came out of Egypt by Moses.

17But with whom was he grieved forty years? was it not with them that had sinned, whose carcases fell in the wilderness?
