Hebrews 3:13-15

King James Version

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

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

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